総統大本営
The Wolf's Lair (German: "Wolfsschanze"; Polish: "Wilczy Szaniec") served as Adolf Hitler's first Eastern Front military headquarters in World War II. The Organisation Todt constructed the complex, which became one of several "Führerhauptquartiere" (Führer Headquarters) in various parts of Central and Eastern Europe, for the start of Operation Barbarossa—the invasion of the Soviet Union—in 1941.
