Under the shield there is a beautiful clock, carved in stone and elegantly made, which probably gave its name to the new construction. Clock that at the present time has no function, since only its carved dial persists. Clock that would be replaced, surely in the nineteenth century, by the one that we see below the viewing body.

Everything seems to indicate, according to the chapter acts of the seventeenth century, that the Clock Tower was an annex to the royal prison with which it was connected. On September 12, 1653, it is reported that a prisoner had fled through the tower due to the watchmaker's carelessness, which is why he would be punished and replaced. Watchtower from where you can see the streets and people of Andújar and from where the work rhythm of its neighbors was set. At the present time, the Clock Tower is, without a doubt, one of the most representative elements of the monumentality of the city of Andújar and an inherent part of the morphology of the Plaza de Santa María

On the west front and halfway up we find the imperial coat of arms of Carlos V and a clock carved in stone. In the first ornamental element, a double-headed eagle carries the imperial crown and the golden fleece borders the shield. In the right-handed canton the lineage of the Trastamara and of the Habsburgs and in the sinister that of the House of Avís, which correspond to Carlos V and his wife Isabel de Portugal, respectively. Its presence is due to the coincidence of the execution of the work with the reign of Carlos V, since it was customary at the time to leave testimony of the reigning monarch in the new constructions. Imperial shield that also reminds the Andujareños of their loyalty to the monarch in the years of the war of the Communities, forming part of the Junta de las Ramblas. His mayor, Francisco de Vergara, was not of the same opinion, who “felt sympathy for the Comuneros, and when the city found out about the actions he was bringing with them, he was so outraged that in the middle of the Cabildo he removed the staff from the Justice". The emperor was very pleased with the loyalty and obedience of the city and the proof of this was the letter he sent on July 20, 1520, from the city of Îpres, in which he thanked the city's attitude towards him in those difficult times moments.

The only documentary source that exists today on this construction is on its west front and says: "Reigning his majesty and being / corregidor of this city the very magnificent knight Francisco / de Alarcón twenty-four of Granada and its mayor el Bachelor Sancho Díaz / de Baeza ended on August 20, one thousand five hundred and thirty-four years. Mayordomo Alonso Yáñez. "?

At its base is the Municipal Tourist Office, from where you can access the panoramic viewpoint.
