Which mosque in Córdoba became the cathedral of the city after the Christian conquest in 1236?

The Great Mosque of Córdoba became Córdoba Cathedral after the Christian conquest of the city in 1236.

The mosque was expanded over several stages by the rulers of al-Andalus. Abd al-Rahman I began the first major mosque in 785, and later rulers enlarged the prayer hall and added features such as the famous mihrab and maqsura under al-Hakam II.

Its interior is recognized for rows of horseshoe arches and alternating red-and-white voussoirs. After Ferdinand III captured Córdoba, the building was consecrated as a cathedral while much of the mosque structure remained.

A Renaissance cathedral nave and transept were inserted into the former prayer hall during the 16th century. The building is therefore commonly called the Mosque-Cathedral of Córdoba. It should not be confused with the former mosque site in Seville, where the Giralda survives but the main mosque was replaced by a cathedral.
