The name 'EL-DE' is derived from the initials of the building's original owner, Leopold Dahmen.
The basement prison is one of the best-preserved Gestapo detention sites in all of Germany.
Over 1,800 original inscriptions remain on the cell walls, serving as primary historical records of the prisoners' final days.
The building survived Allied bombing raids during the war largely intact, allowing for the preservation of its interior spaces.
The center regularly hosts temporary exhibitions focusing on contemporary human rights issues and the legacy of the Holocaust.
It acts as a primary research center for the 'Stolpersteine' (stumbling stone) project in Cologne.
The National Socialism Documentation Center of the City of Cologne is housed in the EL-DE House, which served as the regional headquarters for the Gestapo from 1935 to 1945. It is the largest local memorial site in Germany dedicated to the victims of the Nazi regime. The permanent exhibition details the history of Cologne during the Third Reich, including the persecution of political dissidents, Jewish citizens, and other marginalized groups. The building features a preserved basement prison complex containing 10 cells used for detention and interrogation. Visitors can observe hundreds of original inscriptions and drawings scratched into the cell walls by prisoners. The center functions as both a museum and a research institution, maintaining an extensive archive and library. It documents the mechanism of terror enforced by the Gestapo at the local level. The site also commemorates those who were deported from the city to concentration and extermination camps.
