Bones and skulls from more than 40.000 people are neatly arranged and used for morbid decoration in the chapel beneath the church. In 1870 a woodcarver was put in charge of the pile of bones the chapel had accumulated through times. With a bit of creativity and a weird sense of humour he furnished the chapel with the bones. Pyramids made out of skulls, a huge chandelier containing every kind of bone in the human body and even a coat-of-arms. Whether you fancy the bizarre taste or not, you won't see anything like it elsewhere.
