Peach's Castle

"So this is Peach's Castle...it's more beautiful than I imagined!"

- Penguru

Peach's Castle (also known as Princess Peach's Castle or the Mushroom Castle  ) is the castle situated within the Mushroom Kingdom and its most prominent landmark. Princess Peach and many Toads, including Toad and Toadsworth, reside in it. The rooms inside the castle vary from game to game, as does the castle's location. Its general appearance was codified in Super Mario 64, where it is characterized by a tall tower supported by four towers along the outside walls. It is usually surrounded by a moat and located in a hilly grassland. Some games also have a town of varying size in its proximity, which is often named Toad Town.

Super Mario RPG: Legend of the Seven Stars
The Mushroom Castle makes its first appearance in a video game in Super Mario RPG: Legend of the Seven Stars. It is home to Princess Toadstool, the Chancellor, Grandma, the Vault Guard, and several other Toads. After being escorted to the throne room by Toad the first time, Mario informs the Chancellor that the Princess is missing after a huge sword pierced Bowser's Keep. Soon, after returning from Mushroom Way, Mario and Mallow find Shysters coming out of the castle's front door, with most of the castle's Toads hiding in the Princess' room. After the leader, Mack, is defeated in the throne room, the first Star Piece is discovered and the castle returns to normal. Later, Princess Toadstool is returned to the castle after rescuing her at Marrymore; however, she escapes from her bedroom window using a parasol, and joins Mario's party while Grandma is disguised as her.

After obtaining the fifth Star Piece, Samus Aran makes a cameo resting in the castle's guest room.

Super Mario 64 / Super Mario 64 DS
The Mushroom Castle is the main hub in Super Mario 64 and later in its remake, Super Mario 64 DS. It contains many rooms with paintings (some of which can be jumped into to access courses) and furniture. The Castle Grounds are surrounded by hills that prevent the player from escaping. When the player defeats Bowser, Princess Peach will emerge from the stained glass window on the front of the castle. When the player gets all of the Power Stars in the game, the cannon in the castle grounds is unlocked, granting access to three 1-Up Mushrooms and Yoshi (or a Luigi rabbit in the DS version) on the roof.

In the original version, five secret Power Stars are obtained around the Mushroom Castle itself. Three are each obtained by talking to certain Toads around the castle. The other two are obtained by catching MIPS around the castle. In Super Mario 64 DS, the Power Stars from MIPS are no longer obtainable, which means only three Power Stars returned in the remake. Three Power Stars were introduced in the remake, which makes a total of six Power Stars that can be obtained at the Mushroom Castle:


 * One can be obtained by collecting eight Red Coins in the courtyard.
 * One can be obtained by Luigi when he goes behind a door in behind the large mirror in the room with the Snowman's Land painting.
 * One can be obtained by catching eight glowing rabbits in total.

New Super Mario Bros.
The castle reappears in New Super Mario Bros. where it is struck by lightning in the beginning (as a diversion while Peach is kidnapped) and can be seen in World 1-1. Since this game, the New Super Mario Bros. series has had a running theme of having Peach's Castle visible in the background of the first level of each game.

Super Mario Galaxy
The castle reappears in Super Mario Galaxy, keeping its design from Super Mario 64. A town adjacent to it and a road leading there are considered a part of the castle grounds, named Castle Gardens in the game. In the beginning of the game, Peach invites Mario to the castle for the Star Festival. When he gets there, Bowser lifts the castle into space and kidnaps Peach. At the end of the game, Rosalina flies Mario to the castle so he can battle Bowser. When Bowser is defeated, the castle is sucked into his black hole, but it is expelled and returned to its original location in the Mushroom Kingdom. Mario (or Luigi) can access the castle grounds when they return to the Mushroom Kingdom after they collected 120 power stars.

New Super Mario Bros. Wii


In New Super Mario Bros. Wii, the castle is featured during the game's opening in which Peach holds her birthday party. After she is kidnapped by the Koopalings, Mario, Luigi, and two Toads immediately chase Peach, and two other Toads back at the castle fire Penguin Suits and Propeller Mushrooms out of a cannon into the Mushroom Kingdom.

The castle is also the location to watch hint movies, which can be obtained by giving star coins to a Toad who resides in the castle during the game. Once again, it can be seen in the background at the start of World 1-1.

Super Mario Galaxy 2
The castle appears very briefly in the opening of Super Mario Galaxy 2. After Mario arrives, he finds it under attack by Bowser, who gloats at Mario and flies away with Princess Peach. Mario then meets two Lumas on the bridge over the moat, one of which turns into a Launch Star and sends him to Sky Station Galaxy. The castle also appears at the end of the credits where Mario and friends have a party for saving the galaxy.

Super Mario 3D Land
In Super Mario 3D Land, if the player waits for a while on the title screen without pressing, they can enter Peach's Castle. There are five Toads here, and Mario can practice his moves in the castle. The place where the red Toad stands is inaccessible, as it is sticking up, which can be seen while stepping behind the tower or by switching to 3-D. The castle can also be seen in the opening and ending cutscenes of the game. Like in the New Super Mario Bros. series, the castle also appears in the background of World 1-1, alongside the Tail Tree.

New Super Mario Bros. 2
Like in New Super Mario Bros., Peach's Castle makes a cameo in New Super Mario Bros. 2 in the opening and in the background of World 1-1. It has the same appearance as in New Super Mario Bros. Wii. As in New Super Mario Bros., however, it cannot be entered. It also appears in the hidden area of Course 3 of the Gold Classics Pack.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe


Peach's Castle in New Super Mario Bros. U, New Super Luigi U, and New Super Mario Bros. U Deluxe appears to be in the same location as in New Super Mario Bros. Wii, and can again be seen in the background at the end of Acorn Plains-1. However, this iteration has a large moat surrounding the castle (as in Super Mario 64 and other games), an extra floor, as well as two towers on either side of the central tower. In the games' openings, Bowser and the Koopalings kidnap Princess Peach and take hostage over her at her own castle, which is the final area of the main game. Bowser and Bowser Jr. await the player at The Final Battle, which takes place at the top floor of the castle.

Super Mario 3D World
In Super Mario 3D World, the castle is briefly seen in the opening cutscene as the protagonists (Mario, Luigi, Princess Peach and Toad) take a walk on a starry night full of fireworks and meteors. The castle appears to have its design from Super Mario 3D Land this time around, but the main doors now have a rounded shape, and are blue with three spots, resembling a mushroom, and the grounds surrounding it are blocked by grassy hills.

Super Mario Run
During the events of Super Mario Run, Peach's Castle along with other buildings are destroyed as Bowser tries to destroy the Mushroom Kingdom. However, if the player plays Toad Rally frequently, the castle will be rebuilt and will expand over time.

Super Mario Odyssey
Peach's Castle appears in Super Mario Odyssey. It can be glimpsed in the opening cutscene, but it, like the rest of the Mushroom Kingdom, can only be visited after completing the game. Its design is heavily based on its appearance in Super Mario 64, and features several references to that game.

The roof of the castle can be accessed by throwing Cappy onto a nearby Scarecrow, which creates a temporary set of stairs. Yoshi can be found on top of the roof like in Super Mario 64, albeit encased in a Yoshi Egg; breaking the egg will release Yoshi and allow him to be captured. A Power Moon can be found on one of the castle's towers.

Behind the castle is a small ledge where Goombette can be found, and in the castle's moat is a Warp Pipe blocked off by a Berry. They can both be accessed by draining the moat, which is done by removing the four poles located underwater; this will also play the "puzzle solved" tune from Super Mario 64. The Warp Pipe takes Mario to a painting of the Ruined Dragon, allowing him to rematch the boss.

The castle's interior is heavily based on the main room of the first floor of the castle from Super Mario 64, complete with a rearrangement of "Inside the Castle Walls" as the background music. Toadette can be found inside the castle, and will give Mario Power Moons in exchange for accomplishing certain achievements. Two Power Moons can also be found there, one of which is collected by standing on the sun rug at the center and looking at the ceiling, which is a reference to how the Tower of the Wing Cap is entered in Super Mario 64. Three regional coins can be collected behind Princess Peach's throne, and the kingdom's Hint Art can also be found inside the castle. Like in the rest of the Mushroom Kingdom, the Power Moons obtained in the castle have the appearance of Power Stars, and play the corresponding jingle from Super Mario 64 when collected.

After 999 Power Moons are collected, the castle's tallest tower will be covered by a giant top hat. Climbing on top of it and throwing Cappy at the glowing spot will trigger a short cinematic, showing a display of fireworks as a triumphant rearrangement of the level clear tune from the original Super Mario Bros. plays.

Super Mario Maker 2
Peach's Castle plays a key role in Super Mario Maker 2's Story Mode. In it, Chief Toadette and her group of Toads have just finished building the castle, but Undodog appears and steps on a Reset Rocket, causing the castle to be erased. The mode revolves around Mario going on jobs requested by various characters in order to collect coins to have the Toads rebuild the castle.

Super Mario-Kun
Peach's Castle has appeared a few times in Super Mario-Kun. It also takes in different appearances according to the game the volume is based on.

Mario Kart 64
The castle first appears in Mario Kart 64 in the track Royal Raceway. It has the exact same design as in Super Mario 64. Players have a choice to explore the grounds if they wish, but they cannot enter the castle itself. The Award Ceremony also takes place at the castle where the top three racers will drive there to celebrate after winning. In the reappearance of the course as a retro course in Mario Kart 8, the physical appearance of Peach's Castle and the area around it are changed. Furthermore, the entrance to it has been blocked. Thus, racers can no longer explore the area around Peach's Castle.

Mario Kart: Super Circuit
In Mario Kart: Super Circuit, Peach's Castle can be seen in the background of Rainbow Road atop Bowser's Castle, just like in Paper Mario. It also appears in Peach Circuit, Mario Circuit 1, Mario Circuit 4 and Battle Course 3 as an object in the background.

Mario Kart: Double Dash!!
The castle appears in Mario Kart: Double Dash!! twice: once on Mario Circuit, and again in the background on Mushroom Bridge in Grand Prix mode, just before the first tunnel. In Mario Circuit, the castle is completely cut off from the road and separated from the track by walls. Also, in Mushroom Bridge the castle can be spotted vaguely obscured by fog in the background. This castle is very cartoon-like compared to its other appearances.

Mario Kart DS
In Mario Kart DS, the castle reappears once more in its iteration of Mario Circuit, where the castle is situated on a large lake in the middle of the track. It also appears in Peach Gardens, where the player drives at the back gardens of the castle.

Mario Kart Wii
Peach's Castle appears yet again in Mario Kart Wii, once again on Mario Circuit. Like in Super Mario Galaxy, there is a small town near it. Shy Guys and Hammer Bros. watch the race as they sit on the fences surrounding the castle and houses. The typical Mushroom Kingdom hills can be seen in the background along with a rainbow. Yellow sunflowers are neatly placed along the grasses of the track and a hot-air balloon labeled "MARIO" floats and travels over the grounds.

Mario Kart 7
Peach's Castle appears in Mario Circuit from the game, Mario Kart 7, and it is the first time the player is allowed to drive through the castle.

Mario Kart Arcade GP DX
Peach's Castle reappears as a course in Mario Kart Arcade GP DX simply titled "Peach Castle". Players are once again able to drive inside the castle, although it is much larger in scale than in Mario Kart 7, and it features pieces of character artwork that pop out of boxes in the background similar to jack-in-the-boxes.

Mario Kart 8
In Mario Kart 8, yet another Mario Circuit is built around Peach's Castle. The castle appears to be in a different location from its previous appearances and is on a large hill in the center of the track. It also appears in Royal Raceway with an updated design.

Mario Golf (Nintendo 64)
Although a course titled "Peach's Castle" appears in Mario Golf for the Nintendo 64, the castle itself does not make an appearance.

Mario Golf: World Tour
Peach's Castle is seen in the background of Peach Gardens, a course from Mario Golf: World Tour.

Paper Mario
The castle was once again taken over by the Koopa Troop during the events of Paper Mario. In the beginning of the game, Princess Peach invites Mario and Luigi to a party at the castle. However, while the Mario Bros. (and numerous other guests) are having fun, Bowser hatches an elaborate plan that causes his castle to rise into the stratosphere under Peach's Castle, taking the Princess' castle with it. Many of the party guests are imprisoned and Bowser throws Mario out of a window, sending him spiraling back toward the Mushroom Kingdom. Peach is once again forced to be a prisoner in her own castle.

When Mario visits Shooting Star Summit in the prologue, Princess Peach's room is visited by Twink, a Star Kid who offers to help Princess Peach. After every chapter of the game (except the last), there will be an intermission in Peach's Castle when the player controls Princess Peach to collect information for Mario from Bowser's diary, talking Koopatrols and Hammer Bros, Gourmet Guy, the 64th Trivia Quiz-Off, etc.

In the end, Mario, Goombario, Kooper, Bombette, Parakarry, Lady Bow, Watt, Sushie and Lakilester (with the help of the Star Spirits) fly to Bowser's Castle and make their way up to Peach's Castle. The team finally confronts Bowser and Kammy Koopa on the roof of the castle, and defeat both of the villains, sending them flying off the castle and returning it to its rightful place in Toad Town.

When Mario enters the castle at the beginning of the game, there is a Toad guarding Peach's room. If Mario talks to him enough times, he will become annoyed and let Mario explore the room (however, he insists that he not touch anything). There is also a guest room turned Toad House later in the game, which is also the last Toad House in the game.

Paper Mario: The Origami King
In Paper Mario: The Origami King, Peach's Castle makes its first appearance in the series since the first installment, complete with a similar-looking interior.

At the start of the game, Mario and Luigi are invited there to celebrate the Origami Festival. Inside, Peach's appearance and behavior towards Mario is different, having been transformed into origami by King Olly. When he refuses to be turned into origami as well, Peach sends him down a pit through a trap door hidden in the castle's sun rug. In the aftermath, the castle is overtaken by a series of multicolored streamers, lifted into the sky, and placed on top of a mountain as Olly takes over the Mushroom Kingdom.

Mario Party 2

Mario Party 7
At the end of a Party Cruise game in Mario Party 7, there is an end-of-game ceremony that takes place at Peach's Castle in the MSS Sea Star. Here, Toadsworth announces the game's current scores and gives out the three Bonus Stars to the players based on their performance during the game. When it's time to reveal the Superstar, all four (or eight) contestants will enter the castle to determine the champion. Once they get to the top of the castle, the doors will open and the winner is revealed. That player (or team) is the superstar. The castle can also be seen on a painting in the Duty-Free Shop.

Mario Party 8
Peach's Castle appears in Mario Party 8 in the background of the minigame Crank to Rank.

Mario Party: The Top 100
In Mario Party: The Top 100, Peach's Castle reappears in the background of the minigame Crank to Rank from Mario Party 8.

Mario & Luigi: Superstar Saga / Mario & Luigi: Superstar Saga + Bowser's Minions
In Mario & Luigi: Superstar Saga, and its 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, the castle plays a very minor role. The castle grounds can be explored at the start of the game, and the castle can be viewed from Hoohoo Mountain in the original game. Mario's battle with Bowser takes place inside Princess Peach's throne room, but the castle interior cannot be explored.

At the beginning of the game, Princess Peach receives a gift from the Goodwill Ambassador from the Beanbean Kingdom at her castle, but the ambassador and her assistant soon reveal themselves (Cackletta and Fawful in disguise) and steal Peach's voice. Peach's voice is replaced with bombs, which blow up the castle. Later in the game, it is revealed that who is stolen the voice of is actually Birdo in disguise, and the real Peach is hiding behind a curtain with Toadsworth when the fake Peach is receiving Cackletta and Fawful.

Mario & Luigi: Partners in Time
In Mario & Luigi: Partners in Time, the castle is the main traveling point of the game, nearly identical to how it was used in Super Mario 64. The music is also a cover version to the aforementioned game. The castle held all of the Time Holes leading into the past in the entire game.

There are many items and coins and the castle is home to one of the game's three item shops. There are 2 bosses the player fights in there, one against Junior Shrooboid and the other the last boss in the game; Shrowser. Goombas can also be fought in the basement area.

In the past, the castle has been taken over by the Shroobs, who turned it into Shroob Castle, the final dungeon in the game.

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
The princess' castle reappears in the sequel to Mario and Luigi: Partners In Time, Mario & Luigi: Bowser's Inside Story and its Nintendo 3DS remake, Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.

The game begins at the castle, with Mario and Luigi traveling through the main interior to the meeting room. The meeting is about the Blorbs that have infected much of the Mushroom Kingdom. The meeting is soon canceled as Bowser comes into the meeting, angered by the fact that they don't believe he is there to solve the unknown disease. After Mario defeats him, Peach and Starlow send him out of the castle. Later on, Bowser now under the effects of the vacuum shroom enters the meeting room as everyone leaves, inhaling everyone in the room. Bowser then ends up knocking out, and Fawful appears, sending him out of the castle yet again.

Later in the game, Fawful takes over Peach's Castle, which serves as the final area of the game. In the original game, the castle doesn't look too different except in ruins. In the remake however, the castle is changed to dark purple, the windows are blocked off, Fawful's logo is put everywhere, the interior is much darker and there are dark clouds above the castle the whole time (in the original game, the dark clouds were only present during the final battle). Fawful also transforms the entire castle into a giant robot, which Bowser battles as his final giant boss. After the defeat of Fawful and the Dark Star, the castle is changed back to its old self.

Mario & Luigi: Dream Team
The castle makes a brief cameo in the opening of Mario & Luigi: Dream Team, as it is the place where the invitation to Pi'illo Island is given.

Mario & Luigi: Paper Jam
The castle makes an appearance as the starting location in Mario & Luigi: Paper Jam. It is also the place where Luigi knocks down the book off a bookshelf in the cellar of the castle containing the Paper Mario world. Peach's Castle also includes an Item Shop, a Gear Shop, and later unlocked in the game, a Battle Card Shop. Eventually, the castle gets wrecked by Neo Bowser Castle with cannonballs, leaving the castle in ruins.

Mario vs. Donkey Kong 2: March of the Minis
Peach's Castle can be seen drawn in the background of the first floor, Mushroom Mayhem, of Mario vs. Donkey Kong 2: March of the Minis. Peach's Castle appears as the sixth floor as well, under the name Toadstool Castle.

Mario vs. Donkey Kong: Minis March Again!
In Mario vs. Donkey Kong: Minis March Again!, Peach's Castle is visible in the background of Rooftop levels.

Mario vs. Donkey Kong: Tipping Stars
Peach's Castle can be seen in the extended background of Swirling Courtyard in Mario vs. Donkey Kong: Tipping Stars.

Mini Mario & Friends: amiibo Challenge
Peach's Castle can be seen in the extended background of Balloon Float Castle in Mini Mario & Friends: amiibo Challenge. It can also be seen on the map within range of these levels.

Yoshi's Island DS
Peach's Castle made a small cameo in the intro. When the Toadies are kidnapping babies, Baby Peach is taken from her castle, along with Baby Mario and Baby DK from their respective houses. It is later seen in the credits when the stork takes her back.

Super Princess Peach
In Super Princess Peach, the castle was affected by the Vibe Scepter and Bowser's minions captured Mario, Luigi and Toad while Princess Peach, Toadsworth and another Toad were enjoying a walk. Also, in this game the castle bears six or eight towers supporting the outside walls. If not, it can be explained that the rear of the castle is wider than the front and would require symmetrical placement of towers, therefore allowing only four towers to be visible in the opening scenes.

Fortune Street series
Peach's Castle also appears as a game board in both Itadaki Street DS and Fortune Street.

Mario Sports Mix
In Mario Sports Mix, Peach's Castle returns as a court and background element for Mushroom Cup tournaments.

The main gimmick of this court is sprinklers that turn on and off. In dodgeball, the water acts as the dividing line between the two sides of the court. When the water goes down, players can move anywhere on the court, even the other team's side. In basketball, it acts as an obstacle to stop players from getting to the hoop. In hockey, it blocks the puck from going into the goal immediately. In volleyball, it will cause the ball to bounce back.

Captain Toad: Treasure Tracker
The castle also appears in the ending of Captain Toad: Treasure Tracker, where it fulfills the same purpose as in Super Mario 3D World, appearing in the background as Mario, Luigi, Peach, and Toad are walking.

Mario + Rabbids Kingdom Battle
The castle returns as the hub world of Mario + Rabbids Kingdom Battle. The castle cannot actually be entered in this game, but it can be circled around while accessing various nearby locations.

Monopoly Gamer
Peach's Castle is the fifteenth property on the game board in Monopoly Gamer. It is one of two properties in the Dark Blue Color Set (along with Bowser's Castle).

Castle grounds
The player begins the game in the castle grounds. A sealed cannon is found near the lake to the right. After the player obtains all 120 Power Stars (150 in the remake), the cannon will open and the player will be able to launch themselves to the top of the castle roof, where the player will find Yoshi, who will give Mario 100 extra lives and an enhanced Triple Jump. Also, up there is a Cap Block holding a Wing Cap. In the DS version, Yoshi is seen on the roof only in the introductory cutscene, due to the fact that he is now a playable character. However, Luigi's final rabbit can be found on the castle roof, as well as a ? Block holding a Power Flower (or a feather if the player uses Mario). The roof in Super Mario 64 DS features a small fence around the area where the three Mushrooms are found. It is possible to get to the top of the castle by climbing down the tree when the moat is not drained, or by a special technique all of the characters have to get to the roof without even using the cannon. A moat surrounds the castle, and it can be drained during gameplay if the player stomps on the two columns in the basement. After the moat is drained, the player can enter The Secret Under the Moat. There is also a waterfall, which acts as the exit of Behind the Waterfall.

First floor
After entering the castle, the player will find Toad, who will say to go to the Bob-omb Battlefield portrait, the only course that has not been sealed by Bowser at the time. There is also a locked door that leads to the second floor. There are also two wooden doors, which both lead to the Boo-infested hallway, the courtyard, and the stairs to the basement. A door to the right of the main room will lead to the princess's room, which hides The Princess's Secret Slide. The stairs are located between two pillars, each with two coins on them. A door nearby leads to the castle's Rec Room (only in the DS version). The Big Star Door to the left of the main room is where Bowser resides in the level Bowser in the Dark World. A portrait of Princess Peach is found at the end of the corridor. However, the deceiving portrait will turn into an image of Bowser as the player walks down the corridor. In the middle of the main room, a sun in the form of a rug will send the player to the Tower of the Wing Cap (or ? Switch in the remake) when they look at the sun shining from the ceiling. A 3-star door to the right leads into the Jolly Roger Bay main hub room. Its room has two squares in the wall, to the left and right of the entrance each. Going into the one on the left rewards a 1-Up Mushroom to the player's character. The square on the right leads to The Secret Aquarium level.

Second floor
After the player unlocks the door on the first floor, ascending a set of spiral stairs will lead the player to the second floor of the castle. It is a round room with portraits adorning all areas of the wall. A set of stairs will lead to yet another Big Star Door and ultimately the third floor. There are two doors found opposite each other on the outside wall. The first leads to a room that contains several portraits leading to Tiny-Huge Island. The other contains a mirror that runs through the center of the room. The player can become Vanish Luigi to pass through the mirror in the remade game.

Third floor
The third floor consists of a small, round room with a clock seen directly opposite the door. There are two small niches in both sides of the wall, each leading to a different course; the one to the left will warp the player to Wing Mario Over the Rainbow (named Over the Rainbows in the remake), and the one on the right will warp the player to Rainbow Ride. Above the door of the third floor is yet another Big Star Door, where a staircase will lead to the final battle (Bowser in the Sky). However, 70 Power Stars (80 in the remake) are needed to break the spell of the endless stairs.

Basement
The basement is the lowest area of Peach's Castle, as it is just below ground level. It can be entered through the set of stairs that descend near the first floor. It consists of many areas all linked together by doors. One of the lower areas of the basement is made up of shallow water. An area found at the front of the castle basement is initially completely flooded with water from the castle moat. However, the moat can be drained by ground-pounding two pillars. After the player has done so, the water will drain and a door that was previously inaccessible leads to the castle grounds.

After the water is drained, a 1-Up Mushroom can be spawned by touching the four corners of the tunnel area.

Description and location
In most games, the castle is normally gray marble, but in some games, it is white and even a light cream (Super Princess Peach). Since 1996 it has kept its original highest tower emerging from a wider circular tower underneath - both always in the center of the castle. Normally the main feature of the castle is a rectangular or square shape, with nearly always four towers supporting this part. The roof is nearly always a shade of red, but in Mario & Luigi: Superstar Saga it was a pale orange.

A window is usually present at the front of the palace. There is an image of Princess Peach embedded, painted or carved onto the window. In Super Mario 64, this was the part of the castle Princess Peach was concealed in and is only released when Bowser is defeated.

In Super Mario 64 and Super Mario 64 DS, the castle is a huge palace with many rooms and secrets. Despite having many rooms, there are no regular "living" rooms, such as a bedroom or kitchen. Most of the rooms simply have a large painting in them. The castle also has a basement, the floor of which is oddly coated with water. The castle grounds were also quite spacious in this game. There are plenty of trees that can be climbed up, and the land itself is quite large. A body of water surrounds the castle, which eventually leads into a small pond. In this game, the castle is reached via Warp Pipe.

In Paper Mario, the castle differs radically from its 64 counterpart. The palace is still large and has a great number of rooms, but each room has a purpose (there is a library, a bedroom, and many storage rooms), and the lobby is connected to the ballroom. The castle grounds are also much smaller, with a simple fountain and one or two trees outside the castle. Much of the castle's surrounding land was lifted into the air with Bowser's castle, which may explain the seemingly shrunken land; however, even when Mario finally reaches the castle to confront Bowser, no moat can be seen. The castle has no warp pipe leading to it, as it can easily be reached from Toad Town.

In Mario & Luigi: Partners in Time, the palace was again, like Paper Mario, big and had actual "living" rooms. This castle however was different from the Mario 64 and Paper Mario versions and the garden looked very different (there were no trees either).

In Mario & Luigi: Bowser's Inside Story, the castle's conference room was seen in the intro. It is eventually taken over by Fawful and served as the final area in the game.

In Super Mario 64, there was a courtyard located behind the castle but it was not visible from the front or roof of the castle in the main gardens. However, the main part of the castle could be seen from the courtyard. The courtyard introduced the magic and mystery of Peach's Castle that the Power Stars seemed to have control over. The courtyard in both the original Super Mario 64 and in the Nintendo DS remake was infested with Boos. Big Boo's Haunt and another secret level were hidden in here.

Differing from the castle in Super Mario 64, in Super Mario Galaxy, the castle now has a balcony and several windows. The castle still has the body of water connected to it, but is now close to a nearby town. Also different from the older version, this castle's outside is more detailed.

Also in Super Mario Galaxy, the cutscenes show a more detailed top tower than when playing as Mario in the Star Festival.

In Mario & Luigi: Bowser's Inside Story the castle was controlled by Fawful and was planned to use it against Bowser when he would arrive, Bowser then defeated the castle in the devastating battle. In the 3DS remake, the castle has been completely transformed inside and out, and is much darker with more Fawful motifs, such as the dome he fought in from Mario & Luigi: Superstar Saga, which makes a few appearances, notably in the entry of the castle. The windows are blocked off, and machinery is in clear view built into the castle, inside and outside, foreshadowing the giant battle with Bowser. The brickwork surrounding the castle is also now metallic, and the stained-glass portraits of Princess Peach now have Fawful's face on them.

In New Super Mario Bros. Wii, the castle has fewer windows, no moat, more detail than its DS predecessor, and looks more remote than Super Mario 64/DS and Super Mario Galaxy.

In Super Mario Galaxy 2, the castle looks like the castle from Super Mario Galaxy. The balcony from Galaxy is still present, and there are now several vases full of flowers on the grounds. During the invasion of Bowser, several meteors hit the grounds, blocking off the east half of the grounds.

In Super Mario Odyssey, the castle was largely similar in design to in Super Mario 64, although it possessed a flagpole on top, as well as a balcony. In addition, the turrets surrounding the castle are now shown to be hanging over rather than directly connected to the moat. In addition, the brochure for the kingdom in that game revealed that the reason it had a stained glass image of Peach near the top of the castle was as a form of comfort for the inhabitants of the kingdom, as Peach sometimes was absent from the kingdom, either due to Bowser abducting her or simply leaving on her own accord, with the citizens creating the stained glass window. In addition, aside from the turrets of the main castle, there were also additional turrets that were originally watchtowers, but were converted into art storage depots that contained magical paintings.

In Super Smash Bros. Melee, the castle largely had the same design as Super Mario 64, although the central turret had part of the top removed, and also possessed platforms.

Other castles
Peach appears to have more than one castle. A completely different one is seen in Mario Hoops 3-on-3. It stands on a gigantic and poorly structured rock out in the sea. This castle is also visible from Koopa Beach. The castles of Super Mario Bros. and its sequel, Super Mario Bros.: The Lost Levels, are also said to be in the Mushroom Kingdom and invaded by Bowser. The Mushroom Castle in Super Mario RPG: Legend of the Seven Stars also has a radically different design, as it predates the traditional design from Super Mario 64.

In the Modern version of the Fire minigame for Game & Watch Gallery and Game & Watch Gallery 4, the main setting is a burning castle that presumably belonged to Princess Peach, with Mario and Luigi needing to evacuate Toads, Yoshis, and Donkey Kong Jrs. into a nearby Mushroom carriage. In the comic series Super Mario Adventures, Peach's Castle has a slightly different design, resembling a medieval castle.

Items found
In addition, the following special items are available only to Princess Peach.

Area Tattles

 * ''This is Peach's Castle. But we just came out of Bowser's Castle! I've got a funny feeling about this... I wonder where Princess Peach is being held captive. I think we should brace ourselves, Mario.
 * ''This is the first floor hall of Princess Peach's Castle. There are so many doors, though. Where on earth can Princess Peach be?
 * '' Boy, what happened here? This is even messier than my room back home! It looks like nobody ever puts anything away in here.
 * ''That's a pretty huge drawer over there. I bet a person could fit inside! If they wanted to, that is... Hey, there's a bed, too! This must be a guest room.
 * ''It's a kitchen. I'm just guessing, but I bet this is where they make the meals. The castle's head chef probably cooks all the meals, don't you think? I wonder what kinds of savory dishes he knows how to make. Hey, Mario, have you ever eaten here?
