Diocese of Córdoba dedicated to the Assumption of the Virgin Mary and located in the Spanish region of Andalusia. The structure is regarded as one of the most accomplished monuments of Moorish architecture.
According to a traditional account, a small temple of Christian Visigoth origin, the Catholic Basilica of Saint Vincent of Lérins, originally stood on the site. In 784 Abd al-Rahman I ordered construction of the Great Mosque, which was considerably expanded by later Muslim rulers. Córdoba returned to Christian rule in 1236 during the Reconquista, and the building was converted to a Roman Catholic church, culminating in the insertion of a Renaissance cathedral nave in the 16th century.
Since the early 2000s, Spanish Muslims have lobbied the Roman Catholic Church to allow them to pray in the cathedral.This Muslim campaign has been rejected on multiple occasions, both by the church authorities in Spain and by the Vatican.
