The King Friedrich Wilhelm I Fort (Fort Nr. 3), originally known as Quednau, was the largest fort of Königsberg fortification system. The fort was situated at the top of a height and surrounded by dry ditch. There were embrasures for defensive fire. In time of Kongsberg Storm the Fort was of severe resistance. Garrison remains was captured on the 9th of April 1945. After the WWII there was the army division in the Fort. Archeologists have found more than 30 000 objects from the ex- museum “Prussia”, when the division left.
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.
