Worldwide, many places have been distinguished as catacombs even though they lack the first and foremost qualification: dead, interred bodies. The Znojmo Catacombs in the Czech Republic represents these posers, but these underground passages share an interesting history nonetheless. They were mostly built during the late middle ages (14th and 15thcenturies). The primary purpose of these underground mazes was to provide a safe haven from invaders. At times, these subterranean safe havens were self-sustainable for months on end. Fresh water wells and ample storage meant the city’s residents could outlast even the longest calamities.
