Somehow I ended up going from reading about pirates to stumbling on this. Is there anyone other than me who finds this a bit more disturbed than “touching” or “holy”?
The Sedlec Ossuary (Czech: kostnice Sedlec) is a small Christian chapel, located beneath the Cemetery Church of All Saints (Czech: Hřbitovní kostel Všech Svatých) in Sedlec, a suburb of Kutná Hora in the Czech Republic. The ossuary contains approximately 40,000 human skeletons which have been artistically arranged to form decorations and furnishings for the chapel.
