I just found out about this marvel. The eerily cool church, Sedlec Ossuary, is located in the Czech Republic. It's decorated with over 40,000 skeletons, and even has a chandelier made of bones. It's weirdly beautiful, check it out in this video to find out this church came to be decorated like this. Furthermore, it's hauntingly beautiful, and I wonder if there are any ghosts there? I kind of want to see this in person, and yet I'm also totally creeped out, lol.
