The water fortress of Koluvere was established in the 13th century by the bishop’s vassal Lode. The tower fortress, convention hall and cannon tower were built later. This place has been a battlefield both during St. George’s Night uprising as well as during the Livonian war. In 1439 it became one of residences of Saare-Lääne bishop. In the 17th century the fortress was turned into a manor ensemble. In 1771 the empress of Russia – Catherine II – bought it and gave it to her lover – Prince Grigori Orlov. From that time and until 1917 the castle was used by the Russian czar’s family. Later on the building has been used as a boys’ educational establishment and as a nursing home.
At present the castle is in private ownership and being renovated. It is open in advance bookings only.
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.
