Cologne's Third Reich history is poignantly documented in the NS Documentation Centre. In the basement of this otherwise mundane-looking building was the local Gestapo prison where scores of people were interrogated, tortured and killed. Inscriptions on the basement cell walls offer a gut-wrenching record of the emotional and physical pain endured by inmates. Executions often occurred in the courtyard.
