German prisoner-of-war camp in World War II, the site of many daring escape attempts by Allied officers. The castle sits on a steep hill overlooking the Mulde River as it flows through the small Saxon town of Colditz, about 30 miles (48 km) southeast of Leipzig. A former residence of the kings of Saxony, the castle was used in 1939 as a prisoner-of-war camp, and in 1940 it became a maximum security prison for escape-prone Allied officers.

The internal buildings and courtyards were perched 250 feet (76 m) above the surrounding terrain and were enclosed by steep stone walls 7 feet (2 m) thick at their base. Staffed by numerous armed guards and located some 400 miles (640 km) from friendly territory, Colditz seemed to offer no hope for escape. Yet, through ingenious tunneling and various ruses, prisoners on some 130 occasions managed to clear the fortress grounds. A total of 32 prisoners managed to reach the frontier without recapture. Colditz fell to the U.S. Army in April 1945.
