WWII created as an air raid shelter.
1946 to 1955 transformed into an atomic bunker.


Kryt Denis (Bunker Denis) is a World War II air raid shelter for the inhabitants of Brno city center which was 900 m long and big enough for 3,000 people. It is located under Petrov, the hill on which the Katedrála svatých Petra a Pavla (St. Peter and Paul Cathedral) stands. It was named after (Denis's orchard), a small park on the hill. The military denomination was Kryt CO (Bunker CO). The bunker covers an area of 85 m by 60 m and consists of a series of parallel tunnels connected by perpendicular corridors. The bunker has several entrances and a number of emergency exits, a necessity for air raid shelters, as any entrance could be covered by the debris of a bombed building or even be destroyed by a direct hit. After the excavation the corridors were covered by a brick lining. The tunnels have a total length of some 900 m.

The Denis Shelter is currently renovated and might be open to the public in Autumn 2020. It is already listed on the Underground Brno website, but no open hours or entrance fees are given. However, it is possible the opening will be delayed by the COVID-19 pandemic. There is no need for more tourist sites without tourists.
