The Gestapo headquarter is a secret office run by senior officer Otto Flick. Its location is a secret dungeon, at Rue de Gangoine 32, presumably in central Nouvion. Tthe lower part of the dungeon have a cellar with a contraption inside to lower the roof, for interrogation and torturing.
- The location referred to as the dungeon in Allo Allo may be ambiguous. Engelbert Von Smallhausen refer it as a part of the Gestapo headquarters, while in the same scene earlier Helga Engelbert say its a part of the Chateau. Either there are two separate dungeons or the Gestapo headquarters are at the same location (in the underground) as the Chateau.
