The Moorish Alcazaba
The Alcazaba was erected to guard its governors and citizens during the constant incursions and also to dominate the way through the bridge over the Guadiana river as it is stated on the marble commemorative plate ordered to place there by Abd-ar Rahman II after suppressing an uprising in the year 828.
Its walls has a square ground plan of some 550 m (1.804 feet). The wall is 2.7 metres wide and 10 metres high and are made of uneven hewn stones and other material from Roman and Visigothic works. It is surrounded by 25 square turrets.
The main access to the Alcazaba is flanked by two towers and two fronts featuring horseshoe arches. Within it, there is an aljibe (singular Moorish water deposit) built in the subsoil. Close to the river, there is a double staircase that leads to the water deposit, supplied by the seeping of the river. The pilasters proceeding from important Visigothic buildings stand out, they are ornamented with plant motifs like grape clusters and plant trees.
Subsequent excavations have discovered some sections of a double Roman road and the base of an ancient Roman door. Moreover, there are ruins from a stately mansion with peristyle, thermal baths and mosaic paving.
