The Mosque–Cathedral of Córdoba, officially known by its ecclesiastical name, the Cathedral of Our Lady of the Assumption, is the cathedral of the Roman Catholic Diocese of Córdoba dedicated to the Assumption of Mary and located in the Spanish region of Andalusia. Due to its status as a former Islamic mosque, it is also known as the Mezquita and as the Great Mosque of Córdoba.
The mosque structure is regarded as an important monument in the history of Islamic architecture and is considered by many scholars to have been highly influential on the subsequent "Moorish" architecture of the western Mediterranean regions of the Muslim world. It is also one of Spain's major historic monuments and tourist attractions, as well as a UNESCO World Heritage Site since 1984.
The Great Mosque of Córdoba held a place of importance amongst the Islamic community of al-Andalus for centuries. In Córdoba, the Umayyad capital, the Mosque was seen as the heart and central focus of the city.
