Svislach Castle was established as the center of the Duchy of Svislach; it later belonged to the Duchy of Minsk, and from the 14th century to the Grand Duchy of Lithuania. The castle came into the possession of the Radziwill family and one of its prominent owners was Bogusław Radziwiłł. Today it is in ruins.
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.
