On a trip a few years back we were driving from Barcelona to Cadiz. On our way to Valencia we passed through the city of Tarragon where this aqueduct is located, had to stop for a peek. Glad we did, its a pretty impressive structure to last for ~1900 years, took some average photographs. Built in the 1st century BCE, Under Emperor Augustus, the Pont del Diable was constructed as a massive aqueduct that brought water to the city of Tarragona from 15 miles away. Sturdily constructed with two layers of arches, 711 feet still remain to forge a link to antiquity in Catalonia. Besides a link to the Roman Empire, the aqueduct was actually used into the 18th century to bring water to Tarragona, showing the perfection of Roman architecture....The Aqueduct is now part of a green area and trail system. and one of the best preserved aqueducts from the Roman era, its now a UNESCO World Heritage Monument.

The Aqueduct measures 217 meters with a height of 27 meters. It consists of two levels of superimposed arches, with 11 arches on the lower and 25 on the upper. The arches have a width of 6.3 meters and a height of 5.7 meters and a thickness of 1.86 meters. Elevation on the east side is 56.8 meters and the west side is 56.4 meters.

This bridge got its name, Pont del Diablo, from a local legend. According to the story, the devil built the bridge overnight for an elderly couple who needed to cross the river. There was one condition though. The devil would take the soul of the first one who used the bridge. The next morning when the bridge was finished, the elderly couple realized they had made a pact with the devil. The lady then poked the donkey to walk on the bridge....THE END PS, last photo is strictly for scale.
