This sign can be seen at the Wolfsschanze (Wolf's Lair), one of Hitler's many bunkers/headquarters.
On July 20, 1944 a bomb meant to kill Hitler exploded in the Wolf's Lair conference room, injuring Hitler and killing four others. The coup failed and many high level German officers were executed as a result.
