The name of the place is probably of Lombardic origin, meaning meeting place, which is explained by the strategic position of the fortress, controlling from all cardinal pointsa very wide area, and being in visual conact with a whole network of other fortresses and towers. By the end of the X century Salle is mentioned in a document contained in the Chronicon Casauriense, and in 1191 it was included among the 72 castles controlled by the monastery of San Clemente a Casauria.
Later on a number of feudal lords controlled the place, among them the Colonna, Gonzaga, Carafa, d'Aquino e and finally di Genova families. In recent years Baron Mario di Genova worked passionately in restoring the castle, in a bad shape after the 1933 earthquake, and established inside it a museum of local history.
