Multi-purpose civil defense facility Sedanplatz

from Wikipedia, the free encyclopedia

The civil defense multi-purpose facility Sedanplatz is a former nuclear shelter in the Vegesack district of Bremen .

MZA Sedanplatz: Platforms

It is designed as part of the underground car park under the Sedanplatz and should offer space for a good 4,000 people in order to survive for up to 14 days. The facility has been a listed building in Bremen since April 2020 .

planning

During the Cold War in the 1960s and 1970s, the federal government planned shelters for civil protection of the population, which should serve to protect the population in the event of a war. For this purpose, multi-purpose underground garages were built with financial support from the federal government.

construction

The Sedanplatz was just a gravel parking lot until the early 1970s. The construction of the MZA Sedanplatz began in 1973 and was completed in 1975 after a construction period of two years. The construction costs amounted to 13 million DM , of which DM 5 million federal grant. The architects were Theodor and Klaus Rosenbusch.

The shelter is located on the lowest parking level of the underground car park, approx. 12.5 m below the surface. The bunker was divided into two areas, each of which could accommodate 2000 people.

For this purpose, brackets are built into the parking decks that can be equipped with bed beds. The MZA was protected with reinforced ceilings and walls and could be sealed gas- and pressure-tight.

Adjoining rooms

The functional areas with the necessary equipment and devices were housed in side rooms.

Two kitchens were available for catering. There was a small infirmary to treat the injured. There were also washrooms and toilets as well as storage rooms for food, clothing, protective equipment and hygiene items. The bunker guard had its own guard room in order to coordinate the bunker operation and to be able to contact the nearest Warnamt II in Bassum in an emergency .

technology

The bunker was supplied with water via a deep well, which could be stored in a 60,000 liter tank. A 200 HP emergency power generator was able to ensure the bunker's power supply for 14 days. The outside air was cleaned by a ventilation system with sand and activated carbon filters .

use

In addition to protection against contamination by NBC weapons in the event of war , there was also the later aspect of maintaining a shelter in the event of a nuclear reactor accident in the Unterweser nuclear power plant, which is only 40 km away .

After the end of the Cold War, the threat situation subsided in the 1990s. In 2007 the Interior Ministers ' Conference decided to abandon the nationwide protective building program.

In 2010, the Vegesack Advisory Board decided not to change the content of the nuclear bunker under the Sedanplatz underground car park, which is no longer required for civil protection, in cooperation with BREPARK GmbH and the Senator for Interior and Sport, but instead to leave its equipment as it is and to enable the public to gain insights through bunker visits as part of the tourism concept. "

Today (2019) the multi-purpose facility is only used as an underground car park operated by the municipal BREPARK GmbH.

On the day of the open monument or as part of the Vegefest (beginning of October), an initiative that works to preserve the bunker at Sedanplatz offers guided tours through the bunker.
