Château de Salveterra was built by Jacques I of Aragon in 1246 to the border between France and Kingdom of Aragon. It was besieged in 1598 and 1639 by French troops. In the 16th century, the village and castle were abandoned. The castle ruins remain south of the plateau today. It consists of an enclosure protected by a moat, tower, vaulted rooms and a walkway portion with battlements and loopholes.
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.
