The Mosque-Cathedral of Cordoba (World Heritage Site since 1984) is arguably the most significant monument in the whole of the western Moslem World and one of the most amazing buildings in the world in its own right. The complete evolution of the Omeyan style in Spain can be seen in its different sections, as well as the Gothic, Renaissance and Baroque styles of the Christian part.The site which the Mosque-Cathedral occupies has been used for the worship of different divinities since ancient times. Under the rule of the Visigoths, the Basilica of San Vicente occupied this very site, and later, after the Moslems bought part of the plot of land, a primitive Mosque was built. The basilica was rectangular in shape, and for a while was shared by Christians and Moslems.
