During the Cold War, a number of emergency protected hospitals were built in West Germany. One such was in Wedel, to the north west of Hamburg. The stated capacity was around 1,700 beds. The hospital was protected with thick concrete walls and had its own water and power supplies.
It was never used in anger but was activated in exercises in 1975. After the reunification of Germany, the stored medical supplies and equipment were donated as humanitarian aid.
Today it is possible to visit the site as part of a pre-arranged tour through the not-for-profit society Hamburger Unterwelten.
