Puy Foradado Dam, dam in Zaragoza province, Aragon, Spain
The Puy Foradado Dam is an ancient Roman structure built on the Riguel River in Zaragoza Province. It features an arch-gravity design with a distinctive hollow opening through its wall, a technique that reduced weight while maintaining strength against water pressure.
Built in the 2nd or 3rd century AD, the Romans constructed this structure to manage water for settlements and farms in the region. After centuries of use, it eventually fell out of service but remains a lasting example of Roman hydraulic engineering.
The site is easily accessible in a quiet area with minimal tourist facilities nearby. Visitors can freely walk along the old structures and view the stonework from different angles without restrictions.
The distinctive hollow opening that runs through the dam's wall gives it the name Foradado, meaning pierced in Spanish. This clever design not only reduced weight but also allowed water to flow through in a measured way.
