Two trademarks of Andalusia are orange trees and Moorish architecture. The Mezquita in Cordoba is one of the landmarks of the mixed Moorish and Gothic design that is distinctive to southern Spain. Formerly the central mosque of one of the most important cities in the Islamic world, it was saved from destruction after the Christian reconquest of Spain in the 1400s, but a cathedral was built in the middle of it. This tower was built for Muslim calls to prayer and later turned into a bell tower. The clear dusk in Cordoba was lovely.
