This is a snow biome castle. It has many many rooms including two main bedrooms, four servant bedrooms, one closet under the stairs, one bedroom under the stairs, eight bathrooms, two guard towers, kitchen, dining hall, throne room with trap door, potion room, enchanting room, small library, two balconies, two large fireplaces, two bedroom fireplaces, seven staircases, and other things that I am not going to count...I probably miss-counted the things I did count. The main entrance is controlled via redstone switches on the outside and inside. The redstone circuit is under the doorway. The trap door in front of the throne is also controlled with a redstone switch and leads to a small flooded chamber. The enchanting table is mainly for show so it only has a partial charge. You could melt the snow and place this castle anywhere really but it was intended to be a snow castle.
