The Mosque-cathedral of Córdoba (Spanish: Mezquita–catedral de Córdoba), also known as the Great Mosque of Córdoba (Spanish: Mezquita de Córdoba), whose ecclesiastical name is the Cathedral of Our Lady of the Assumption (Spanish: Catedral de Nuestra Señora de la Asunción), is the Catholic Christian cathedral of the 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.
It originally was a Catholic Christian church built by the Visigoths. When Muslims conquered Spain in 711, the church was first divided into Muslim and Christian halves. This sharing arrangement of the site lasted until 784, when the Christian half was purchased by the Caliph ‘Abd al-Rahman I, who then proceeded to demolish the entire structure and build the grand mosque of Cordoba on its ground. After the Reconquista, it was converted to a Roman Catholic church.
In planning the mosque, the architects incorporated a number of Roman columns with choice capitals. Some of the columns were already in the Gothic structure; others were sent from various regions of Iberia as presents from the governors of provinces. Ivory, jasper, porphyry, gold, silver, copper, and brass were used in the decorations. Marvellous mosaics and azulejos were designed. Panels of scented woods were fastened with nails of pure gold, and the red marble columns were said to be the work of God. The primitive part of the building, erected under the direction of Abd-er-Rahman I., was that bordering the Court of Oranges. Later, the immense temple embodied all the styles of Morisco architecture into one composition. The Great Mosque of Córdoba held a place of importance amongst the Islamic community of al-Andalus for three centuries. In Córdoba, the capital, the Mosque was seen as the heart and central focus of the city. Muhammad Iqbal described its hypostyle hall as having “countless pillars like rows of palm trees in the oases of Syria”. To the people of al-Andalus “the beauty of the mosque was so dazzling that it defied any description.”
The main hall of the mosque was used for a variety of purposes. It served as a central Prayer hall for personal devotion, the five daily Muslim prayers and the special Friday prayers. It also would have served as a hall for teaching and for Sharia Law cases during the rule of Abd al-Rahman & his successors. The Great Mosque of Córdoba exhibited features, and an architectural appearance, similar to the Great Mosque of Damascus, therefore it is evident that it was used as a model by Abd al-Rahman for the creation of the Great Mosque in Córdoba.
