The Suda of Tortosa Monument · Tortosa, Baix Ebre, Tarragona A citadel overlooking Tortosa, whose name -la Suda- comes from Arabic and simply means “castle” or “fortress”; the houses built up against its base formed the city's first urban core, sheltered by this fortification which served as its rearguard. Believed to have been built in the 10th century under Caliph Abd al-Rahman III, at the time of the reconquest it was divided into three independent castles, whose possession Count Ramon Berenguer IV shared out among the first knights who stormed the wall, among them Guillem Ramon I de Montcada and Pere de Torrelles i Sentmenat, keeping the third for himself. After the Christian conquest of 1148 it became a royal residence, frequented by Jaume I, and since 1972 it has operated as a state-run parador hotel.
