The first information about the castle at Goriano Sicoli is from the 11th century.
At that time the fort was located on top of the hill, protected by a bulwark and a double ring of walls which were equipped with defensive openings and towers. The village was accessed via three imposing gates: Bagliucci, Baracca and Murro, all equipped with shutters and arrow slits.
Porta di Murro dates from the 15th century. Its pointed arch would orignally have been rounded like those of Porta Bagliucci and Porta Baracca. It still has a damaged marble plaque, featuring two female figures and the form of a lion with heraldic symbols of uncertain origin.
