great mosque of Qurtaba(cordoba)

The Mosque of Cordoba was built during the 9th and 10th centuries and consecrated as the cathedral in 1236. A Jewel of Hispano-Islamic art, the Mezquita, with its 850 columns, double arches and Byzantine mosaics, is a legacy of the Ummayid Caliphate in Spain. In the center of its vista of columns rises a 16th-century cathedral.

The Great Aljama Mosque of Cordoba, begun in 786 by Abd al-Rahman I, is the highest expression of Islamic art in Spain and the most important historic mosque of the West. Its last touches were made by Almanzor in 988, and it was the place of worship for the rulers of the western Islamic empire Al-Andalus.
Important Islamic features include the Minaret, now enclosed and reformed into a Baroque bell tower, the Orange Tree Courtyard, the Mihrab and the forest of columns and arches.
