Alfonso X was the King of Castile from 1252 until 1284. During his reign, he commissioned the construction of a cathedral on the site of a Muslim mosque. After Cádiz’s oldest church was finished in 1263, it was expanded multiple times. In 1596, most of the city was looted and burned by English and Dutch troops. Although some sections of the cathedral were salvaged, most of the existing structure you see was rebuilt by 1602 by architect Cristóbal de Rojas After a replacement cathedral was finished next door in 1838, this became the Parish Church of Santa Cruz.
