Subterranean catacombs under the Jesuit church in Klatovy were built in 1656-1676. Members of the order, as well as notable citizens, noblemen from the surroundings and other benefactors were buried there. Burying in the crypt was ended by the emperor Joseph II's order in 1783.
Thanks to an elaborate system of air circulation bodies in oak coffins were gradually mummified and conserved. The crypt can be visited through the entry on the right-hand side of the church.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
