The oldest part is constituted by a small tower built at the end of the fifteenth century. A few years later the initial volume was extended to form the square plan. The space between the original tower and the perimeter walls was terraced to enhance its defensive capacity against artillery. The fort, despite participating in feats of arms at the end of the sixteenth century in which it was looted and burned, largely maintained its original formal structure until the twentieth century, when after falling into disrepair and dilapidated, it was rebuilt in 1969.
