Jurisics Castle, named after Croatian nobleman Nikola Jurišić. The oldest part was built in the 13th century. The inner castle originally of Gothic style was extended later on. This building complex served as an estate castle and was also converted in the Renaissance and Baroque era. The character of the two islands still can be observed: it is visible that the fortress and the interior of the castle were surrounded by a moat.
During the Little War in Hungary, Pargalı İbrahim Pasha under the command of Suleiman the Magnificent laid siege to the castle in 1532. Jurišić and less than 1000 men defended the castle for 25 days without any artillery, despite 19 assaults.
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.
