There are many curious things in this world, one of the more curious is the Ossuary of Sedlec. Also known as a church of human bone.
The story goes that the Abbot Henry brought back some dirt from the holy land. This of course caused a ruckus and everyone wanted to be buried in a place that had “Holy Land”. Soon though the cemetary was full, but that did not stop them from burying people there. People were removed and stored, eventually the church even had too many bones in storage. With the help of the local architect they deviced a use for these bones and the Ossuary as it is now was born.
