The bunker at Ladeburg bei Bernau to the north east of Berlin, which was constructed between 1982 and 1985, housed the command post of the 41st Anti-aircraft Rocket Brigade “Hermann Duncker“. The two-storey structure complete with garage extensions was built between 1982 and 1985 and commissioned in December 1986 following appropriate functional trials. In an emergency, it was possible to control up to 10 anti-aircraft rocket divisions from here. Taken over by the Federal Armed Forces in 1990, the bunker continued to be used until 1991; after that it was dismantled and then sealed. Since May 2002 guided tours of the site, which has been purchased by the Ladeburg Animal Sanctuary, have been available.
