The Mezquita is one of the most breathtaking examples of Muslim architecture in Spain. It evolved over several centuries and, after Cordoba was retaken by the Christians a cathedral was built inside, destroying part of the mosque. There are many beautiful features including hundreds of marble and stone columns, a lavishly decorated mihrab and the Chapel de Villaviciosa, the first Christian chapel after the recapture.Built in 1371, and in the Mudejar style, it blends in harmoniously with the mosque. The 300 foot bell tower is on the site of the former minaret.
