Between 1941 and 1944, the Wolf’s Lair was the headquarters of Adolf Hitler and the Supreme Command of German Armed Forces. Located in a forest, in the very heart of Masuria, it consisted of nearly 200 buildings, including bunkers, barracks, a power station, a railway station, two airfields, a water supply system and heating plants. The permanent number of personnel at the “Wolf’s Lair” numbered approx. 2000 people. It was here that Claus von Stauffenberg made a failed attempt on Hitler’s life in 1944.
