The castle of Mora d'Ebre (Ribera d'Ebre) is located at the top of the city, from where you get a breath-taking view over the Ebro and its river plain. It was built during the Muslim domination and conquered by Count Ramón Berenguer IV in the 12th century. Later it was a direct witness of the war against the French intruders and the Carlist Wars. Some 350 meters of outer walls, two Arab towers and old outbuildings that lead to a large terrace are preserved.
