Miranda do Douro Dam
About this Place
The Miranda do Douro Dam is a remarkable feat of engineering and a landmark of 20th-century Portuguese energy development. Completed in 1960, it was the first dam built on the international section of the Douro river, inaugurating a cascade of hydroelectric projects that permanently transformed this Iberian border landscape. At 80 metres tall and 82 metres wide at the crest, the dam holds back a broad reservoir that, beyond generating electricity, has created conditions for tourism and recreation in the region.
Hydroelectricity on the Douro Internacional
The construction of the dam was part of a national strategy to electrify Portugal and harness its water resources. The associated hydroelectric power station continues to generate electricity today. The artificial lake created by the damming of the Douro extends several kilometres upstream, forming the natural border with Spain along its entire length.
Landscape and Nature
The Miranda dam reservoir is integrated within the Douro Internacional Natural Park, ensuring protection of its banks and the rich wildlife that inhabits them. The schist slopes descending to the reservoir maintain the typical Mediterranean vegetation of the region and provide critical habitat for numerous bird and reptile species.
River Beach and Recreation
On the shores of the reservoir, the Miranda do Douro River Beach has been developed with full facilities for swimmers and water sports enthusiasts. The calm lake water, sheltered from the wind by the Douro gorge, warms to pleasant temperatures during summer.
