The golden age of Cádiz in the 18th century, thanks to its monopoly on American trade, required a suitable setting for liturgical celebrations, which the old Cathedral of Santa Cruz, despite its venerable age, could no longer provide. Thus, with the financial support of the merchants trading with the Indies, construction began on a magnificent architectural work, designed by Vicente Acero in 1722.The author's genius lies in having given the work an air of originality by combining Spanish architectural tradition with Italian Baroque forms. In this way, the Gothic floor plan with its powerful apse coincided with the rich movement of lines characteristic of Italian architects of the period.Due to the size of the undertaking and the pace of construction, which was always constrained and sometimes suspended by trade, the building underwent several revisions that modified the original plans. In fact, the temple was consecrated in 1838. Among the changes, the Neoclassical style that gradually took hold is noteworthy, although the spirit of Vicente Acero remains dominant throughout the project. These stylistic shifts are evident in the upper sections of the Cathedral: the dome, towers, and the crowning element of the main façade.
