Famous landmarks in London include the Tower of London, Westminster Abbey and Big Ben, all of which can be visited in the game. Koopa Troopas stole artifacts from each of the landmarks - the Crown Jewels from the Tower, a Shakespeare Bust from Westminster Abbey and Big Ben's Minute Hand - and Luigi has to find and return them to the respective landmarks.
In Mario's Time Machine, Mario travels back in time to London circa 1595 to return the stolen Crown of the then-reigning monarch, Queen Elizabeth I. However, Mario only enters the queen's palace, and does not explore any of London. While there, he also talks to one of the queen's servants, one of the queen's handmaidens, and Francis Drake. Mario later travels back in time to 1831 to return a Magnet to Michael Faraday, talking to Sarah Barnard, Charles-Gaspard de la Rive, and a boy who claims to be an heir to the throne of England while there. Later still, Mario travels back in time to 1843, visiting one of London's streets to return Charles Dickens's Inkwell. There, he talks to a grumpy banker, a poor orphan, and Charles's wife, Catherine Dickens. In all three time periods, he leaves the city after returning the important item to its respective owner.
It is also the setting for Mario & Sonic at the London 2012 Olympic Games, corresponding to the setting of the real-life 2012 Olympic Games being held in London.
London was also referenced in The Adventures of Super Mario Bros. 3. During the events of "Reptiles in the Rose Garden", it was mentioned by Luigi as one of the cities that Bowser was planning to attack after he succeeded in taking over the United States of America. However, Mario and Luigi stopped the Koopa Troop before this could happen.
