Frederiksberg is a district of Copenhagen whose current Town Hall took from 1942 to 1953 to complete, due to the shortage of materials during World War II. Beneath its elegant form lies a Cold War Civil Defence Bunker in a splendid state of preservation. Protected by blast doors in a lower basement, the emergency generator for the bunker is still in working order and provides standby power for the Town Hall. Totalling around 400 square metres, the bunker has a large central control room surrounded by smaller rooms for support staff and functions. The teams were mostly civilian, although the police also had a presence. Support functions included a small kitchen,dining area, a lounge, toilets and sleeping areas. Two half-height blast doors provided access to emergency exits. Within the main control room, many maps and manuals were still on display. Especially interesting (and perhaps unique to Denmark?) a ‘resources’ board held tokens denoting emergency and support services (eg red indicated fire applicances). These tokens would have been moved to a large map, indicating their area of deployment and showing what reserves were held. Basic traingulation of any attacks would have been achieved through reports from observers atop nearby tall buildings, including the Town Hall itself. A series of display lights throughout the bunker indicated the current alert level (eg air-raid in progress, bunker in lock-down) and also the presence of senior officials. This light system was still in full working order. The bunker was activated, for example after the Chernobyl disaster, but has not been used in recent years.
