Fårösund is a decommissioned fortress, built from 1885 to 1886. Sweden's capacity to protect its neutrality was questioned after the Crimean War 1854–56. England and France persuaded Sweden to fortify the inlet at Fårö with artillery batteries and naval mines. The fortress consisted of three fixed batteries. At the turn of the century, the batteries were reconstructed. The batteries I and II were given modern quick-firing 57 mm guns, four per battery. In 1919 the fortress was closed down and all equipment removed. After the fortress was closed down and was taken over by the Swedish Prison and Probation Service in 1919, a penitential center was establishment. The fortress had been proposed as a detention center for social dangerous offenders, if and when legislation for such came about.
Today the fortress is a hotel and restaurant.
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.
