The Chapel of All Saints was built on the cemetery of the Cistercians monastery in Sedlec around the year 1400. Abbot Henry brought some soil from Jerusalem and spread it on the ground of the cemetery, which got the fame of the Holy Land. That was the reason why not only the local people, but also the Germans, Poles and Belgians were buried here. In 1318 thirty thousand people, who died during the plague epidemic, were buried here. In the first half of the 15th century during the Hussite wars the cemetery had a maximum area of 3,5 hectares. Later it was gradually liquidated and the remaining bones were stored in the chapel, later below the chapel. In 1511 a nearly blind monk piled them in six pyramids, 10 000 bones in each. On his lines Giovanni B. Santini originated an ossuary after the reconstruction of the chapel. The recent outlook was given to the bones and scalps in the year 1870 at Charles Schwarzenberg´s instance – the interior is decorated exclusively by human bones. Especially the chandelier, made of all the sorts of human bones, is really unique. The ossuary is the largest in Europe. There are bones of about 40 000 people used in the chapel.
