The Puente Romano, a bridge over the Guadiana River that is still used by pedestrians, and the longest of all existing Roman bridges. Annexed is a fortification (the "Alcazaba"), built by the Muslim emir Abd ar-Rahman II in 835 on the Roman walls and Roman-Visigothic edifices in the area. The court houses Roman mosaics, while underground is a Visigothic cistern.
