The Mosque–Cathedral of Córdoba (Spanish: Mezquita-Catedral de Córdoba [meθˈkita kateˈðɾal de ˈkoɾðoβa]) is the cathedral of the Roman Catholic Diocese of Córdoba in the Spanish region of Andalusia. Officially called the Cathedral of Our Lady of the Assumption (Spanish: Catedral de Nuestra Señora de la Asunción), it is dedicated to the Assumption of Mary. Due to its status as a former mosque, it is also known as the Mezquita (Spanish for 'mosque') and in a historical sense as the Great Mosque of Córdoba.
According to traditional accounts a Visigothic church, the Catholic Christian Basilica of Vincent of Saragossa, originally stood on the site of the current Mosque-Cathedral, although this has been a matter of scholarly debate. The Great Mosque was constructed in 785 on the orders of Abd al-Rahman I, founder of the Islamic Emirate of Córdoba. It was expanded multiple times afterwards under Abd al-Rahman's successors up to the late 10th century. Among the most notable additions, Abd al-Rahman III added a minaret (finished in 958) and his son al-Hakam II added a richly decorated new mihrab and maqsurah section (finished in 971). The mosque was converted to a cathedral in 1236 when Córdoba was captured by the Christian forces of Castile during the Reconquista. The structure itself underwent only minor modifications until a major building project in the 16th century inserted a new Renaissance cathedral nave and transept into the center of the building. The former minaret, which had been converted to a bell tower, was also significantly remodelled around this time. Starting in the 19th century, modern restorations have in turn led to the recovery and study of some of the building's Islamic-era elements. Today, the building continues to serve as the city's cathedral and Mass is celebrated there daily.
