The Angevin-Aragonese castle in Agropoli has a triangular shape with three circular towers and stands on the highest point of the headland. Around the walls there is a wide and deep moat which today is visible just on the side of the village and disappears while on the eastern side because of agricultural works and past landslide.
The castle was built on the 6th century Byzantine foundations by the Aragonese reign in the 15th century. The Inside part of the castle is composed of a central square, nowdays used as on open air theater, and on the northern side by the “French Room”.
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.
