Alcalá de Guadaíra is a town located approximately 17 km southeast of Seville, Spain; in recent years the expansion of Seville has meant that Alcalá has become a suburb of that city. Alcalá used to be known as Alcalá de los Panaderos because it provided most of Seville's bread. The town is located on the banks of the Guadaíra River, and watermills built during the Moorish period of Spain can still be found in the area.
