It was in the seventeenth century that Prince Francesco Marino Caracciolo requested the construction of the Tower, whose project was probably drawn up by the great Cosimo Fanzago, who was in Avellino precisely in the role of Caracciolo’s adviser.

However, the architect Giovan Battista Nauclerio finalised the work, where in the past there was a bell tower. In baroque style, the tower was initially on two floors with a squared bosses basement. It was only later that a third level was added with the four faces clock and the “diana”, which rang to signal any imminent danger in the town. Damaged by the earthquakes of 1688 and 1742, the tower was restored at the end of eighteenth century and then again after the seism of November 1980, thanks to the recovery of various original parts.
