The ribbed vaults of the Mosque-Cathedral of Córdoba served as models for later mosque buildings in the Islamic West of al-Andalus and the Maghreb. At around 1000 AD, the Mezquita de Bab al Mardum (today Mosque of Cristo de la Luz) in Toledo was constructed with a similar, eight-ribbed dome. Similar domes are also seen in the mosque building of the Aljafería of Zaragoza. The architectural form of the ribbed dome was further developed in the Maghreb: the central dome of the Great Mosque of Tlemcen, a masterpiece of the Almoravids built in 1082, has twelve slender ribs, the shell between the ribs is filled with filigree stucco work.
