Using existing 19th Century catacombs, German Stettin created this underground shelter in 1941 as a civilian refuge from allied bombing raids. The shelter comprises five levels, with a total depth of 17 metres. Its iron and concrete walls are three metres thick. The longest corridor is about 100 meters and the total area of the shelter is 2,500 square metres.
After the war, the shelter was adapted for use in case of fallout from a nuclear attack, with local Civil Defense training taking place there regularly until the early 1990s. With a number bricked-up passages that lead to uncharted destination, the shelter remains a mysterious place. Today, tours are available. In shelter two thematic routes are available:
– Route “World War II” – the anti-aircraft shelter is presented via a reconstruction of life during bombing raids, a discussion of construction techniques and displays of photographs and artefacts from the War years.
– Route “Cold War” – The shelter’s history as an anti-nuclear defense is presented via a discussion of the adaptation of the anti-aircraft elements of the facility for use in the event of a nuclear attack. Featured are presentations of Polish Civil Defense equipment, activities that took place at the site and displays of propaganda from the period.
