Capilla Castle was built by Moors to the site of ancient Roman fortifications. It was conquered by Christian king Ferdinand III of Castile and León in 1226 and rebuilt soon after. It stands on a crag where it reveals its structure in the shape of an irregular polygon attempting to adapt to the abrupt terrain. A barbican defends the main door, which leads onto the two courtyards. Inside, the cylindrical towers, the half-demolished allure and the remains of a machicolation give you an idea of the defensive nature this castle had.
In spite of its current appearance, you can still see the ruins of the old Arabic walls, both on the south side and the north, and the original stone paving of the staircases and rooms.

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.
