The Sedlec Ossuary in the Czech Republic is a very interesting place.
The church is adorned with the remains of around 70,000 people, many of whom died in the plague in 1318 and during the Hussite Wars in the 15th century.
The church uses the bodies that have been dismembered, de-fleshed and reassembled into decorations including a bone chandelier.
We'd love to see the gift shop...
