It was the first major dam built by the Portuguese state-owned electric company on the Zêzere River.
The reservoir created by the dam is the largest in Portugal by surface area, covering approximately 2,000 hectares.
The dam's arch curvature design was specifically chosen to minimize the volume of concrete required while maximizing structural strength.
The Zêzere River, where the dam sits, is one of the longest rivers flowing entirely within Portuguese territory.
The hydroelectric plant integrated into the structure has an installed capacity of 97 megawatts.
Cabril Dam is an arch dam located on the Zêzere River near Pedrógão Grande in central Portugal. Completed in 1954, it serves both hydroelectric power generation and water storage for the surrounding region. It stands as one of the tallest dams in Portugal, reaching a height of approximately 132 meters. The structure creates the Cabril Reservoir, which stretches for miles and is utilized for water sports and leisure activities. The dam is situated within a valley characterized by rugged, forested terrain typical of the Castelo Branco district. Its concrete arch design is engineered to withstand the pressure of the reservoir while managing river flow. Visitors can access the crest of the dam, providing a view down into the steep gorge of the Zêzere. The surrounding area features numerous hiking trails that navigate the river banks.

Bring binoculars to spot local bird species, including raptors that nest in the nearby valley cliffs.
Ensure your footwear is suitable for walking on uneven, sloped concrete surfaces near the dam crest.
Visit during the shoulder seasons to avoid high heat while still enjoying clear weather for photography.
Do not attempt to swim in areas immediately adjacent to the dam wall due to strong currents and suction risks.
Stay within designated pedestrian areas and follow all safety signage regarding restricted zones.
