A millenary village, located at the top of a hill that overlooks the Tinto river. Its most impressive feature is its two-kilometre-long wall, which entirely covers the city's perimeter.

The city within the confines of the wall preserves some of its ancient layout, and has some remarkable buildings such as the alcázar (fortress) of the Count of Niebla; the church of Santa María de la Granada, an old Byzantine cathedral that was turned into an Arab mosque, only to be transformed into a Gothic-Mudejar Christian church in the 16th century; and the church of San Martín, built over the western mosque, of which at present only the old apse and the rear façade remain. Beyond the confines of the wall, we must point out the Roman bridge and aqueduct.
