Princess Peach's Castle: it's one of the Mushroom Kingdom's most prominent landmark immortalized in playing cards. Tipster Professor Hazard passes this along:

Check out this house of cards that Sasha Fiero over at Snipe Hunt Media made! It's Peach's Castle from Super Mario 64, complete with moat and a Queen of Hearts for the picture of Peach on the front. I thought this might be the kind of thing you guys would want to see.
Yes, see and destroy like the house of cards it is. No, we're not kidding. Nice job, Sasha! Click here to compare. Brian Ashcraft
