This one arch-span was called the Roman Bridge until the end of the 15th century when it was renamed Puente San Miguel (Bridge of Saint Michael). Both names are a misnomer because it is an Islamic construction. In the background are the ruins of Baños Arabes. This 13th century Arab Baths has three chambers for different stages of cleansing defined by horseshoe arches plus brick and marble columns. Water was supplied by a waterwheel and aqueduct from the Arroyo de las Culebras (Creek of the Snakes) near its confluence with Rio Guadalevín.
