Located in the town of Kutna Hora in the Czech Republic, the Sedlec Ossuary has become a popular if somewhat macabre attraction. It's a small chapel under All Saints Church, and the bones of between 40,000 and 70,000 people have been left here, with some remains dating back to the 13th century. The skulls and bones have been carefully arranged in neat piles, and many of them have been used to create decorations and even furniture. Garlands of skulls adorn the walls and there's even a chandelier made from bones. The so-called 'Bone Church' also contains a coat of arms made out of bones.
