In the Czech Republic is the world renowned Sedlec Ossuary. It’s a huge mausoleum containing the remains of 40,000 to 70,000 people located underneath a small Catholic chapel. Most of the dead were killed by the Black Plague and Hussite Wars during the 14th and 15th centuries.
As you might imagine with that many bodies, the mausoleum was getting crowded. Around 1500, a nearly blind monk was tasked with stacking the bones in the chapel itself to save space. By the late 1800′s a woodcarver by the name of Frantisek Rint had begun arranging the bones in artistic patterns.
The results are really really reallllllllly creepy. Just check out a few pictures from the place. You’ve been warned.
