This structure is generated by the Better Dungeons mod in snowy biomes. The castle has redstone lamps throughout. A switch at the entrance to the path upward lights most of the bottom half of the castle. A second switch in one of the towers lights the walkways above. Walkers guard the castle with their Walker Boss.
The Entrance into the walls contain a Village that have some Walkers guarding and food in the chests. The
main entrance into the castle has a long dining table with the throne at the end. There are some chests in the upper room.
