OMG...The Sedlec Ossuary is a basement of a Roman Catholic church in Kutna Hata, Czech Republic (about one hour east of Prague). It contains the bones of at least 40,000 people who died of the plague in mid 14th century. As people were dying, the survivors would place bodies near the door to the church and they were subsequently buried. But they ran out of room. According to Wikipedia, in 1511 the bones were exhumed by a monk and piled in the basement. Then in 1870 a woodcarver organized them into 4 pyramids in the corners of the church basement( skull image with coins below) and then did the unthinkable: used bones to decorate the basement.
Many were arranged artistically to form a chandelier and this coat of arms (see the skull to get an idea of the scale of this). Sad, fascinating, interesting and I felt the energy. Brings up all kinds of thoughts about whether this is an ethical use of human remains. My perspective --- YES. I'd rather have my bones displayed in an interesting way that provokes thought and emotion then be stuck in the ground forever. Why not? WOW. This place is not to be missed.
