After the Catholic Monarch Ferdinand II conquered Granada in 1492, he began to convert, expel, imprison or execute the Moors in Castile and Aragon. This included converting all Islamic mosques into Christian churches. This 14th century minaret is all that remains of Ronda’s original mosques. The upper level, formally used by the muezzin to call the faithful to prayer five times a day, was refashioned into a bell tower. However, the lower two levels of the Church of San Sebastián retain their original Islamic design.
