Brněnská kostnice (Brno Ossuary), Czech Repblic. Public Domain.

Until recently nobody knew about the existence of the Brněnská kostnice (Brno Ossuary) under St. Jacob's Square. It was rediscovered in 2001 on a routine exploratory archaeological dig for a new construction project. What they discovered was an underground passage with the bones of approximately 50,000 people. As there is no historic document about this ossuary, it is unclear how it was created. Most likely the bones of the people were removed from the church cemetery of St Jacob church to make room for more burials. The cemetery existed at least since the 13th century, but in the 17th century it was not big enough anymore. There is a theory that people were buried in the cemetery, but after 10 to 12 years they were replaced by the next dead. The bones, which were not gone at that point, were relocated to the osarium (bone house). The remains are believed to be from the 17th and 18th century, a result of an explosion in population in connection with frequent epidemics of plague and cholera. The result is an enormous amount of bones, second only to the catacombs of Paris.

The ossuary was abolished in 1784 as a part of the Josephine reforms. Church cemeteries were closed for hygienic reasons. The remains of the graves were placed in the crypt, the cemetery wall was torn down, and the area was paved with excess tombstones. The ossuary was walled and forgotten.

The bones were originally piled in neat rows filling the tunnel from the floor to the ceiling. But during the centuries the ossuary was flooded by water which relocated the thousands of bones and washed them into a big messy pile. For several years the archeologists worked on returning the crypt to its ordered pre-flood state. Finally, it was reopened as part of several underground sites under the name Kostnice u sv. Jakuba (Ossuary at St. Jakuba).
