Bishop's Castle III

@Ana Lúcia: Yes it is! The guy is a bit of a nut actually... but he's done this all himself, by hand, using stone and metal. It's not in the picture, but he's working on a wall to go around it and a dungeon of sorts now.

@Simon Hawkings: Here's a link to info about the castle. It's nestled in the San Isabel National Forest in Colorado, USA.
