Erected as an observatory to defend the town in the 15th century on a commission by the Orsini – Del Balzo family, the feudal lords of Minervino Murge, it later on became a bell tower.
The tower has recently being restored and brought back to its ancient splendor giving it a characteristic yellow colour. The old gears of the clock (19th century) have also been restored and are now exhibited inside the tower. The hours are now marked by an electronic mechanism.
