From December 1935 to March 1945, the Gestapo worked in the EL-DE-Haus. At this historic place, visitors are guided through all chapters of Cologne's Nazi history in the permanent exhibition "Cologne in National Socialism". The cellar of the building houses the Gestapo Memorial. On the walls of the cells are touching original inscriptions and drawings of prisoners.
