Brno Ossuary is home to an estimated 50,000 skeletons of victims of the Plague, cholera and 30 year war. This is currently known as the 2nd largest Ossuary in Europe.
The bones of victims were left alone for 200 years when they were rediscovered by accident in 2001, the crypt was eventually opened in 2012 after restoration.

Many crypts were abolished for hygiene reasons in the late 1700's. They were paved over and forgotten.
