Aldeadávila Dam, Hydroelectric dam in Aldeadávila de la Ribera, Spain.
The Aldeadávila Dam is a concrete arch-gravity structure spanning the Duero River between Spain and Portugal. Multiple spillway gates manage water discharge through a series of channels that maintain the dam's structural stability.
Construction began in the 1950s following international treaties between Spain and Portugal for shared river management. The project represented a major step in hydroelectric development on the Iberian Peninsula.
The dam structure and surrounding landscape served as filming locations for international movies including Doctor Zhivago and Fast X.
The site is accessible from both the Spanish and Portuguese sides, with viewpoints for observing the water masses and surrounding landscape. Be aware that access to certain areas may be restricted and the best views are often found from the Portuguese side.
Hidden beneath the surface is a vast machine hall carved into solid rock, where the actual power generation takes place. This concealed industrial architecture makes the facility a remarkable example of underground energy production.
