Wolfsschanze (Wolf's Lair)

The Wolf's Lair is located in the Masurian woods near the town of Rastenburg in what was then East Prussia and is now northeastern Poland, near the modern town of Kętrzyn. The complex was constructed in 1941 as Adolf Hitler's primary military headquarters for Operation Barbarossa, the invasion of the Soviet Union.

Yes, the ruins are open to the public as a tourist site near Kętrzyn, Poland. The bunkers were deliberately blown up by retreating German forces in 1945, but the massive concrete ruins—with walls several meters thick in places—remain and can be explored by visitors.

On July 20, 1944, Colonel Claus von Stauffenberg detonated a bomb inside a conference room at the Wolf's Lair in an attempt to assassinate Adolf Hitler. The blast killed four people, but Hitler survived with relatively minor injuries because the briefcase containing the bomb had been moved behind a heavy table leg.

The Wolf's Lair was a sprawling fortified complex containing dozens of reinforced concrete bunkers, barracks, and support buildings spread across a heavily guarded and camouflaged area in the Masurian forest. At its peak, it housed over 2,000 military and civilian personnel during the campaign against the Soviet Union.
