Giralda is the name given to the bell tower of the Cathedral of Santa María de la Sede in the city of Seville.

The lower two thirds of the tower correspond to the minaret of the old mosque of the city, from the late 12th century, in the Almohad period, while the upper third is a superimposed construction in Christian times to house the bells.

At its top is a ball called a jar on which stands the bronze statue that represents the Triumph of Faith and that has the function of a weather vane, certainly beautiful.

During the period of Almohad domination, the city of Seville became the capital of Al-Andalus, which brought an update of its infrastructures to the city, proceeding to the construction of some large buildings.

The construction of the Giralda starts on a 3.60 meter foundation, very little wider than the tower itself, and which constitutes the only foundation of the building, according to archaeological studies, a thick layer of mortar and a simple improvement of the terrain. in which the remains of previous Muslim constructions in the area were included.

From there another three meters of masonry emerge from the sidewalk, with a series of marble slabs from Roman times.

The stones that were used tayud al adi were extracted from the wall of the palace of the Alcazar of Ibn Abbad. The walls of this palace had defensive characteristics. The stones were lowered without the need for stairs, since these walls were ascended by a slope suitable for horses.

On June 19, 1195, the emir Abu Yaacub al-Mansur defeated Alfonso VIII of Castile at the battle of Alarcos. Upon returning he ordered the realization of large golden bronze spheres to be placed on top of the minaret. They were placed on March 10, 1198 in the presence of the emir.

These were on a large iron column that was founded on the top of the minaret.

These four golden balls or apples strung on a vertical stem are called yâmûr in Arab culture and have been used, although not always, to crown mosques.
