Laufen Castle is a square-shaped castle overlooking the Salzach river that was built for the Archbishop of Salzburg in the 15th century. It is assumed to be built on the ruins of an ancient Roman structure and was first mentioned in the reign of Bishop Vergilius of Salzburg, and once again in the 13th century. On March 29, 1166, Emperor Barbarossa held court here.
During World War II the castle was used first as a prisoner-of-war camp for officers, Oflag VII-C. Then In May 1942 the officers were transferred to another camp, and the castle was used as an internment camp Ilag VII housing some hundreds of men deported from the Channel Islands of Jersey and Guernsey and some American civilians that had been caught in Europe by the declaration of war by Germany on the United States on 11 December 1941.
