To the west of the Yanguas town, on the edge of the cliff, is a limestone castle that controlled the access to the Ebro valley. It is not certain when it was first built and it is possible that it was built when Yanguas received its own town charter. However, the architectonical style suggests that it was built in the 14th century.
Recent restoration works have given the castle back the dignity it deserves to be a heritage site and have made it possible to understand the defensive function of the unique columned and cobbled weapon yard. Another feature that has been restored is the tower on the north-western side.
It has a quadrangular floor plan and towers on each of the corners. On the walls, there are battlement hexes, a chemin de ronde and narrow loophole windows. There are also two gates, one on the west and the other on the east side, that gave access to the castle.
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.
