The Castle of Montemiletto rises on the mountainous relief in a dominant position over the surrounding landscape and the valley crossed by the Calore and Sabato rivers.
The Norman castle, known as "Castle of the Lioness" belonged to the feudal lords de Tocco. According to some historians the castle was probably built in the Longobard age between the VIII and the IX century. Severely damaged in 1419 by the siege placed there by Count de Tocco, it was transformed into an aristocratic residence in the 16th century, in the late Renaissance period.
The building hosted Charles III of Bourbon twice. An Angevin fief of the de Tocco family, it passed to the Durazzo, Caracciolo, della Leonessa and again to the de Tocco family, who reacquired it in 1448. The de Tocco became Princes in 1567 and administered the feudal rents until 1806.
