Cordoba's Mosque
What was once the second largest mosque in the world, just behind Mecca, is currently the most important monument of Islam in the West. It was declared a World Heritage Site by UNESCO in 1984. Initially built by the Umayyad emir Ab al-Rahman I in 785, the mosque we know today is the result of successive enlargements and, finally, the Christian intervention, which turned part of it into a Cathedral. Here you'll feel an indescribable emotion.
