Apparently some few years, years being centuries ago, some fellow threw some holy soil from the Holy Land on the cemetery in the small Czech town of Sedlec. The place rapidly became a place where people desired their bones interred. Its been going on for 400 odd years. Bones began to pile up until in the 1870s they decided to go art nouveau on the place and made the bones part of the decor! Welcome to the Sedlec Ossuary!
