Other Ancient Monuments in Spain

Spain's single monuments here are Roman aqueducts, among the finest left from the empire. The Aqueduct of Segovia strides across the lower town on 167 granite arches laid without mortar, about 28 metres high at Plaza del Azoguejo; Les Ferreres, the Pont del Diable in pine woods north of Tarragona, is a two-tier bridge whose water channel you can walk along; the Peña Cortada aqueduct inland from Valencia is a half-day hike through tunnels, a rock cut and a bridge over a ravine.
