The construction of the Przezmark castle started at the beginning of the 1300s continued until c. 1350. In the next centuries the stronghold was repeatedly converted because it was adjusted to new functions: the seat of a commune head, a prosecuting attorney and a convent. Since the beginning of the 16th century the castle belonged to the bishops of Pomesania as to later come into hands of the families of von Egmon and von Verdte. After the period of the private owners, came the period, in which the stronghold performed the function of the seat of the offices to finally decline and to be disassembled in the 18th century The first of the old names of the castle suggests that before the Teutonic times there existed the Prussian merchant settlement. The tower that has survived till our time emerged around 1329 and is called the Prisoner-Of-War Tower.
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.
