The work was carried out by the masters Domingo and the Morisco Ameçot, a resident of Calatayud.

It was built in 1560 by the master Domingo and the Morisco Ameçot and was carried out, specifically, to place a clock that was going to regulate the life of the town from that moment, probably following the Zaragoza influence of the Torre Nueva, that had the same purpose.

The Mudéjar tradition tower consists of two bodies crowned with an octagonal top.

The upper body is built of brick and is also square but smaller; it is divided into two floors, the lower one contains the clock on one of its sides, and the other three have double blind semicircular windows.

The octagonal top has eyelets on all sides, and from there the transition is made to the spire that covers the structure.
