The supersecret factory of submarine repairing in Balaklava was opened for everybody's view only in 2003. This unique project was started in 1957, builders worked almost all the day, in three shifts. And the construction was over in 1961. The underground base of the factory served as the military object during the cold war. This object is the building of anti-nuclear protection. In case of danger the factory could automatically and airtightly close and accommodate all the Balaklava population. There was a bakery, storehouses and a hospital, so people might live there for 3 years. The whole area of all rooms and halls is about 5100 square metres.
