Badajoz stands on the banks of the Guadiana River and was originally a pre-historic camp. Its urban history, however, dates back to the Arab period, although the region also saw a great deal of Roman agrarian activity. One of the most interesting emblems of the city, the Alcazaba, was built during the Almohade period and consists of a walled site incorporating various buildings which are worth a closer look, such as the 'Torre de Espantaperros' (literally 'dog scarecrows') and the Palace of the Dukes of Feria, which now houses the Provincial Archaeological Museum. This magnificently Arab-influenced city also displays other shining moments which have managed to resist the passing of time, with relics such as the Trinitarian Convent, La Soledad Church, the cathedral and a great many bridges, gateways and city walls giving the city its characteristic charm. No visit to the city would be complete without checking out the old town and in particular the ever so unusual Plazea Alta and the Plaza de San José. The city also has a rich epic history and has traditionally been a meeting point and border between Spain and Portugal.
