Nachrichtenbunker Gisela, Cold War communication bunker in Giessen, Germany.
The Nachrichtenbunker Gisela is an underground military communications center with four separate command levels organized into two groups called Hansa I and Hansa II. The rooms feature thick concrete walls of about 1 meter in depth, designed to protect against 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 ended, the facility was converted for various civilian purposes over the following decades.
The complex now hosts the Musik- und Kunstverein Giessen, which regularly organizes exhibitions and cultural events within one of its buildings. This use gives the site a new purpose and brings together people interested in art and music.
The site now functions as office and educational space for companies and the university, though not all areas are open to the public. Visitors should check ahead which parts of the facility are accessible.
Divers discovered evidence of fire damage and military equipment in 1992 within one of the flooded command rooms. These findings offer glimpses into the actual conditions near the war's end.
