Bowser's Museum

Bowser's Museum was where Bowser stored his stolen historical artifacts, and was only featured in Mario's Time Machine. Bowser, using his Timulator, went back in time and stole valuable objects of historical significance to put on display here. In the MS-DOS and SNES versions, it is located within Bowser's castle, whereas in the NES version, it is its own building. In the museum, Mario uses the time machine to return the objects to their right times, foiling Bowser's plot.
