Between 1935 and 1945, the citadel housed the Army Gas Protection Laboratories (HGL), a facility of the Army Ordnance Office for the development of gas protection equipment and research into nerve gases such as tabun, sarin, and soman.



The tour sheds light on this barely visible and previously little-researched part of the citadel's Nazi history – up until its handover to the Red Army on May 1, 1945. The tour also explores the stories and myths surrounding these days.
