Fodor's Expert Review Alcazaba

To get to this sturdy square fortress, built by the Romans and strengthened by the Visigoths and Moors, continue west from the Museo Nacional de Arte Romano, down Suárez Somonte toward the river and city center. Turn right at Calle Baños and you can see the towering columns of Templo de Diana, the oldest of the Roman buildings. To enter the Alcazaba, follow the fortress walls around to the side farthest from the river. Climb up to the battlements for sweeping river views, or go underground to see the aljibe, or cistern.
