Visit one of 19th-century Spain's most ambitious engineering achievements, set against a sweeping landscape of gorge, cliff, and reservoir.
What to see
- The Pontón de la Oliva dam, begun in 1851 as part of the Canal de Isabel II water supply project, one of the earliest large-scale masonry dams built in Spain, and still a striking presence in the landscape
- The dramatic Lozoya river gorge and surrounding sierra that frame the dam, making the site as scenic as it is historically significant
- The nearby ruins of the Romanesque-mudéjar Hermitage of the Virgen de la Oliva, and the Dehesa de la Oliva archaeological site, where remains of a Carpetan-Roman settlement reveal pre-Roman and Roman occupation
What to do
- Explore the reservoir's edge and gorge paths for panoramic views of the water and cliff faces
- Visit the hermitage ruins, set among ancient oak trees just a short walk from the dam
