I built this in survival. It's filled with many paintings and odd entities. I describe the story behind a few of the paintings in books on lecterns. I'm proud of the redstone that is required for the entry. Visitors need to drop a diamond into a cauldron in order for the gate to open. Also dinnerbone chicken.
