The Old Town of Policastro is enclosed by medieval walls of Norman origin, dating from the time of King Roger I (11th century), and is dominated by a fortified castle. Policastro Bussentino also has other ancient monuments of great historical and artistic value.
The Castle of Policastro Bussentino stands out and was formerly a Byzantine fortress built in the 6th-7th century at the end of the Greek-Gothic War when Bussento passed under the dominion of the Byzantines, who built a fortress on the highest point of the hill.
In the 14th century the castle was enlarged and strengthened by Giacomo Sanseverino (1290-1364), as we can read on the marble inscription above the door to the east: Magnifico Domino Iacobus de Santo Sevirino, of 1309.
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.
