The Historic Centre of Cordoba now comprises the streets surrounding the Great Mosque and all the parcels of land opening on to these, together with all the blocks of houses around the mosque-cathedral. The Historic Centre of Cordoba creates the perfect urban and landscape setting for the Mosque. Criterion (iii): The Historic Centre of Córdoba is the highly relevant testimony to the Caliphate of Cordoba (929-1031): this city - which, it is said, enclosed 300 mosques and innumerable palaces - [was] the rival of Constantinople and Baghdad. The Historic Centre of Cordoba maintains its material integrity and there are no elements threatening it. There is also a Municipal Office for the Historic Centre with specialized technicians and administrative personnel to manage the guardianship and to promote the Historic Centre of Cordoba.
