Stalag Luft III was a Luftwaffe-run prisoner-of-war camp during World War II that housed captured air force servicemen. It was in the German province of Lower Silesia near the town of Sagan (now Żagań in Poland), 100 miles (160 km) southeast of Berlin. The site was selected because it would be difficult to escape by tunneling.
Checkpoint Charlie was the name given by the Western Allies to the best-known Berlin Wall crossing point between East Berlin and West Berlin during the Cold War.
