As there are no documentary sources, the exact chronology is unknown, but an approximate timeline can be established thanks to two historical events that, presumably, must have taken place within the setting of the church of San Pedro in Alagón: the first was when King Alfonso III summoned the Royal Court in 1288 and the second, the wedding between Pedro IV and his first wife, Maria of Navarre, in 1338. By this latter date, the Mudejar church may have been completely constructed.

The bell tower has an octagonal footprint and its internal structure is typical of Almohad minarets, in which an exterior tower is wrapped around an interior structure, with a stairway nestled between the two and covered by vaulting consisting of narrowing courses of bricks. It is located at the southwest corner of the temple, divided into rooms on four levels, originally covered by spherical caps, which were later removed to house the counterweights for the clock.

The decorative motifs include intertwined mixtilinear arches, diamond and lozenge shapes, angled brick work and zig-zag details.

The tower consists of three sections, each separated from the next by an overhanging brick impost molding. The first section acts as a solid foundation with the lower half of the walls sloped at an angle to create greater stability; it lacks ornamentation, featuring just a few slit-type openings and a sun dial on the southwest side dating from 1649.

All the sides of the second section of the tower display the same ornamentation, as if the façade were a decorative tapestry. This section has three parts, each narrower than the one below it, separated by friezes of angled brick. The lowest part features intertwined mixtilinear arches, the middle part is composed of grid of diamond shapes made of crisscrossing lines and the upper part has half diamond shapes forming stepped crenellations.

The third section of the tower, as the belfry, has been modified more than the others. There are two distinct levels of apertures separated by a frieze of angled bricks, in addition to a strip of double zig-zag patterns, which functions as a parapet for the openings at the top. On each side of the lower half of this section there is a large pointed arch in which coupled windows with lancet arches resting on an octagonal colonette are set, while the upper half features smaller openings with pointed horseshoe arches, arranged two on each side of the tower. Some of these openings have been altered to house the bells and replaced with round arches.

A parapet wall runs around the top of the tower and a bell gable is set in one side. This latter detail is not original, but was added during a later remodeling.
