Tower of Victoria
In The Super Mario Bros. Super Show! episode "The Adventures of Sherlock Mario", Mario, Luigi, Toad and Princess Toadstool ventured to the Tower of Victoria to stop Professor Kooparity, Mouser, Tryclyde and a Koopa Troopa from stealing the Retro Router from the tower by hiding in suits of armor. Unfortunately, they ultimately failed to do so.
As mentioned above, the tower resembles a warped version of the Tower of London, with even the trees in front of it being bent and warped. Among the various objects inside the tower are suits of armor, a giant magnet and an equally large, swinging ax in it as well. The Retro Router was also originally located in the tower, behind a large, barred cell.
