Nachrichtenbunker Gisela, Cold War communication bunker in Giessen, Germany.
The Nachrichtenbunker Gisela is an underground military communications facility in Giessen, Germany, divided into four command levels organized into two groups called Hansa I and Hansa II. The rooms are surrounded by concrete walls about 3 feet (1 meter) thick, built to withstand bombing.
The bunker was built in 1934 on the grounds of the Verdun Barracks and served as a German Wehrmacht communications center until March 1945. After the war, the facility was gradually converted for civilian use over the following decades.
The bunker now hosts the Musik- und Kunstverein Giessen, which organizes exhibitions and events inside one of the buildings on the site. Visitors can see contemporary art and meet people who gather around music and visual arts.
The site is partly used as office and educational space today, and not all areas are open to the public. It is worth checking in advance which parts of the facility can be visited.
In 1992, divers found traces of fire and abandoned military equipment inside one of the flooded command rooms. These findings give a concrete picture of conditions at the site in the final weeks of the war.
