Czech Republic Katakomby Klatovy

In Klatovy Czech Republic, there is a large crypt underneath a Jesuit church. Jesuit priests were put in oak coffins between 1676 and 1783, and there were as many as 200 bodies inside the crypt. There were ventilation vents and wells which allowed good circulation of air and as a result the remains were mummified with even their hair, clothes and jewelry preserved. Regrettably when the church was redeveloped the conditions changed in the crypts and the bodies began to deteriorate, so 140 bodies were buried in a nearby cemetery. The ones that survived are displayed and kept well-ventilated inside glass coffins so that people can view them.
