The aqueduct was constructed without the use of mortar, relying solely on the weight and precision fitting of the limestone blocks.
The upper level's arches were designed with a slightly varying span to accommodate the terrain and structural stresses.
It is one of the few surviving examples of Roman hydraulic infrastructure where the original stone conduit channel remains largely intact at the top.
The structure was integrated into a larger hydraulic network that included bridges, tunnels, and tanks to serve the Roman provincial capital.
Local tradition calls the monument 'Pont del Diable' (Devil's Bridge) based on a legend involving a bet between the Devil and an elderly woman.
The Ferreres Aqueduct, also known as Pont del Diable, is a preserved section of a Roman-era water channel located north of Tarragona. It stands 27 meters high and 249 meters long, constructed from dry-stone blocks without mortar. The structure features two levels of superimposed arches, totaling 11 arches on the lower tier and 25 on the upper. Built during the 1st century AD, it was part of a larger 25-kilometer system supplying water to the ancient city of Tarraco from the Francolí River. The site is a designated UNESCO World Heritage site as part of the Archaeological Ensemble of Tarraco. It is surrounded by a forest park, allowing visitors to walk across the top tier of the structure. The engineering design utilized a precise gravitational gradient to transport water efficiently over long distances.
The forest clearing at the base of the aqueduct provides a complete view of both tiers of arches.
Wear sturdy, grippy hiking footwear, as the trails around the site are uneven, rocky, and can be slippery.
Bring sun protection and water, as there is limited shade once you exit the immediate forest area near the structure.
Explore the marked forest paths to view the aqueduct from different elevations and angles.
Do not attempt to climb the vertical exterior stone walls, as the ancient masonry is fragile and protected.
Walking on top of the aqueduct is restricted in certain areas for safety and preservation; follow all posted signage regarding where you are permitted to walk.
