The town of Kutná Hora owes its origin to the silver mines which gained importance during the economic boom of the 13th century. At that time a lot of people traveled to this city to find their wealth. However a plague struck and killed so many of them that in the local cemetery no more bodies could be buried. Therefore a chapel was built to deposit the bones. Nowadays this ossuary in Sedlec contains approximately 40,000-70,000 human skeletons which have been artistically arranged to form decorations and furnishings for the chapel.Kutna Hora Church
