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.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
