The Puente Romano — properly Puente Medieval — crosses the Duero at the foot of the old town, below the cathedral and the castle remains. It is a long, low bridge of 16 arches, built in the 12th century on older foundations, and it gives the best views of Zamora's riverside silhouette: the cathedral dome, the castle battlements, and the old town walls reflected in the slow-moving Duero.
The bridge is open to pedestrians and the walk across and back takes about ten minutes. The Parque del Castillo and the riverside promenade below the old walls are good for a longer walk; in summer, the bars and terraces along the river at the bridge foot are the most pleasant place in the city to sit in the late afternoon.
