Sedlec Ossuary in Czech Republic There's a website with pics of chapel decorations made from 40,000 to 70,000 skeletons http://www.sedlecossuary.com/Photo-gallery.html
Dear GOD!!! (pun intended ) What the hell?!? They couldn't come up with better "decorations" than that? That is just to creepy to think about any furthur.
I can't imagine what the energy must feel like in there. I wonder if there was a spiritual/magical purpose for using bones in the design?
From the website: Here's a link to a few more if you're curious. http://atlasobscura.com/category/ossuaries
