The origins of Gesualdo Castle can be traced back to the Middle Ages during the Lombard conquests in southern Italy in the 7th century. It was founded either by the legendary Knight Sessualdo or by Radelchi, Prince of Benevento, as a defensive outpost. The first documented records date back to the 12th century under Norman rule, with William of Altavilla as the first lord. The castle gained importance during the Norman-Swabian era and became a prominent fortress in the region.
Carlo Gesualdo, a descendant of the Norman line, transformed the castle into a Renaissance-style mansion in the late 15th century. Over the centuries, the castle suffered damage and looting during various conflicts, including the Franco-Spanish War and the arrival of French troops in 1799. It underwent significant renovations in the 19th century and was designated as a site of historical and artistic value in 1913. The castle was severely damaged in the 1980 Irpinia earthquake and has undergone ongoing restoration efforts. Currently, a portion of the castle is open to the public, and future plans include establishing a polyphony education high school within its premises.
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.
