From 784- 786 AD, Abd al-Rahman I built the Mezquita, or Great Mosque, of Córdoba, in the Umayyad style of architecture with variations inspired by indigenous Roman and Christian Visigothic structures. Later caliphs extended the mosque with more domed bays, arches, intricate mosaics and a minaret, making it one of the four wonders of the medieval Islamic world. After the Christian reconquest of Andalucía, a cathedral was built in the heart of the mosque, however much of the original structure remains. It can be found in the Historic Centre of Córdoba, a recognized World Heritage Site.
