Under the Tarsia lordship, Belmonte was besieged several times: during the invasions of Charles VIII and Louis XII of France, between 1495 and 1503, and again in 1528 under the French marshal Lautrec. The Tarsia were succeeded by the Ravaschieri Fieschi, of the Counts Fieschi di Lavagna, a family of Genoese bankers. Feudal tenure of Belmonte is recorded to have been purchased from the Tarsia for 28,220 ducats. Under the Ravaschieri churches were constructed in Belmonte, fortifications built and palaces laid out, including the Palazzo Ravaschieri Fieschi della Torre. In 1619 the title of Prince Belmonte was granted to the Ravaschieri Fieschi by King Philip III of Spain.
