The Tower is a witness to the ancient castle, built in 1387 by Gian Galeazzo Visconti, lords of Verona. It was the keep of the castle and was located at the center of a double circle of walls, as evidenced by the Carta dell'Almagià, depicting the Veronese territory in 1400. The Visconti complex was raised on a pre-existing fortress, probably dating back to the 12th century. The bell tower is an elevation from the end of the 1700s and the beginning of the 1800s and hosts one of the most complete Veronese bell concerts (fourteen bells).
