The Capuchin Crypt, Italy, is decorated with the bones of four thousand Capuchin friars. The walls and ceilings are covered in displays and delicate sculptures crafted entirely out of human bones. Skulls peer at you from every nook and cranny. Even the hanging lights are made out of human bones. There's a large clock composed of entirely of vertebrae, foot bones and finger bones. One of the strangest sights are the tiny angel sculptures decorating the halls, which have human hip bones for wings!
