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 Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
