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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
