Under the shield is a beautiful watch, carved in stone and of elegant bill, which probably gave name to the new construction. It is a clock that at the present time has no function, because of it only its cultivated sphere persists. Clock that would be replaced, surely in the 19th century, by the one we see below the looking body.

Everything seems to indicate, according to the capitular records of the 17th century, that the Clock Tower was an element attached to the royal prison with which it was communicated. On September 12, 1653, he reported that a prisoner had fled through the tower because of the watchmaker's neglect, which is why he would be punished and replaced. Surveillance tower from where the streets and people of Andújar are seen and from where the work rate of their neighbours was marked. At the present time, the Clock Tower is certainly one of the most representative elements of the monumental city of Andújar and part of the morphology of the square of Santa Maria.

On the west front and at half height we find the imperial shield of Charles V and a watch carved in stone. In the first ornamental element, a bicephalous eagle carries the imperial crown and the gold Toison borders the shield. In the right canton the lineage of the Trastámara and the Habsburg and in the sinister of the House of Avís, which correspond to Charles V and his wife Isabel of Portugal, respectively. His presence is due to the coincidence of the execution of the work with the reign of Charles V, for it was customary at the time to leave witness to the reigning monarch in the new constructions. An imperial shield that reminds the Andujareans of their fidelity to the monarch in the years of the war of the Communities, as part of the Junta de las Ramblas. It was not in that same view his mayor, Francisco de Vergara, who "had sympathy for the Communists, and knew the city of the management he brought with them, was so outraged, that in the middle of Cabildo he took away the rod of justice." From the loyalty and obedience of the city the emperor was very pleased and proof of this was the letter he sent on July 20, 1520, from the city of Ipres, in which he thanked the city's attitude towards his person at those difficult times.

The only documentary source that exists today on this construction is on its west front and says: "The great knight Francisco / Alarcón twenty-four of Granada and his major mayor Sancho Díaz / Baeza, who is the king of this city, is now the only one who has been the author of this city. Mayordomo Alonso Yáñez."

At its base is the Municipal Tourism Office, from where you can access the Panoramic Mirador.

The Clock tower, built in the late 14th century, is about 12 meters high. It sits on a stone socket, it is quadrangular, its silvery is not entirely regular, it is distributed internally on four levels, it conserves the almenate and also, on two of its faces, balconies with the function of matacan; on another, matacan ménsulas; while on the north-west one has been placed a named watch, where the matacan and its ménilas were first located.

In 1985 it was declared Good of Cultural Interest.

According to the description of several authors, 3? 4? 5? more than a watchtower would be a chastisement. Built in well-trimmed masonry, its plant is cylindrical with a semicircular wall that protects the entrance. It is located in height (about 2 meters above the ground level) and still retains remains of wood lintel from the door and its cap. There must have been a second floor, as inside the tower remains of beams from the wooden roof that separated both floors. It has two overlapping interior rooms and a terrace. The bottom of the tower is solid. The plants were covered with semi-spherical vaults, communicating with a 1.18 meters wide terraced staircase.

In general it is kept in good condition, although a great crack threatens to break it down

This tower is the only thing left standing in the medieval defensive system. It is about 25 meters high to the parapet of the terrace and is a square base. The entrance is east and is located at 1.90 meters high. For it you can access a square room covered with brick vault. A little bit diverted from the center on the ground, a circular pebble is preserved, excavated in the rock.

The first floor is accessed by a staircase built on the north and west walls, which has a square room of 7.45 metres on its side. It is covered with a slightly pointed brick vault supported by two pointed arches of stone and brick. These stand on the north and south walls. The light is received from open saetas in the center of each wall. The staircase on the south wall is on the second floor. It is identical to the first, although the arches are based on the east and west walls. On the east wall there is a balcony, previously amattacanado, that was looking out for the entrance of the tower that is left in its vertical. This balcony was accessed by two straits. From the second floor you can access the terrace by a staircase on the west wall.

On the floor of the first floor, near the corners, built on the floor, there are four large ceramic silos and with 1.20 meters deep. They are inserted into the thickness of the underlying vault, which is the ground floor cover. On the second floor there are four other smaller ones. They all served to store grains or liquids. On the corners of the terrace of the tower there are still canes that were holding amattacan balconies.

The Tower is Well of Cultural Interest.

This castle reached the second-rank level at the time of the Constable Iranzo, played an important role in taking sides, like Andújar, on the realistic side when in 1465 the king's enemies placed Jaén, and became famous when, six years later, the warden Diego Frías stopped and ordered a rival of the Constable, Don Fernando de Acuña, son of the Count of Buendía and no less than nephew of the Archbishop of Toledo, to be locked in his tower.
In fact, the castle, of small dimensions, was formed by a cylindrical tower with an almond parapet, as Martin drew it from Ximena Jurado. A stone from the upper tower seems to have an inscription, probably Arabic. There is no trace of this tower in the village. However, the head of the church presents a lock that could correspond to the remains of the castle. This solid semicircular wall of masonry could be reused from a large round tower, sister of those of the Rus and El Marmol castles, in the lands of Baeza.
This turret was declared Good of Cultural Interest in 1985.
