You gotta click on that to get the full effect. It’s near Prague, and it is described quite well on neatorama.com:
The Sedlec Ossuary resides in a small Roman Catholic chapel in Sedlec, Czech Republic. If you didn’t know any better, you wouldn’t have guessed that inside the unassuming building is an ossuary containing about 40,000 human skeletons artistically arranged to form decorations, chandeliers, and furnishings!
In the 13th century, an abbot returned to Sedlec with a small amount of earth from Golgotha, the site of Jesus’ crucifixion, and sprinkled it all over the abbey’s cemetery. This made the grounds of the church a desirable burial site and over centuries thousands of people were buried there.
In 1870, František Rint, a woodcarver, was hired to put the heaps of bones in order. He decided to make a work of art out of the skeletal remains: a chandelier made from skull and bones, a coat of arms of the family that paid him to do the work, and even an “artist’s signature” done in bone, of course.
Mr. Rint, you are my hero. You left behind a work of “super-human” beauty. Thank you.
