Princess Peach's Castle

Princess Peach's Castle is, evidently, the castle belonging to Princess Peach. It makes appearances in a number of Mario games; perhaps the most well-known example is Super Mario 64, where the castle serves as the "hub" of sorts, the link between all the game's areas. The castle is also used as a stage in Super Smash Bros. Melee, is part of a track in Mario Kart 64, and is visited in a number of the Mario RPGs, including Paper Mario and Mario & Luigi: Partners in Time. In Super Mario Galaxy, it is lifted into space by Bowser.

The appearance of Princess Peach's Castle, while always having a red, tiled roof and light grey walls on the outside, displays a number of differences across its many appearances. The interior, in particular, greatly varies.
