Brno Ossuary which is the second largest ossuary in Europe, after the Catacombs of Paris. Another ossuary is Capuchin crypt with mummies of Capuchin monks and some of the notable people of their era, like architect Mořic Grimm or the famous mercenary leader Baron Trenk. Labyrinth under Zelný trh (Cabbage market), a system of underground corridors and cellars dating back to Middle Ages, has been recently opened to the public. These cellars were used mainly for storing food, maturing beer and wine, and as wartime shelters. Originally, the they were not interconnected as they are now – this happened later during the reconstruction in 2009.
