Aqueduct of Luynes
From Wikipedia, the free encyclopedia

The Aqueduct of Luynes is a former Gallo-Roman bridge aqueduct located in Luynes, France.
The remains show a stack of five arches and it is the most famous Roman monument in the Department of Indre-et-Loire, despite its modest dimensions. It is also one of the best preserved of the Northern aqueducts. It was classified a historical monument in 1862 and is owned by the town of Luynes.
It originally had a total length of 1,825 metres (5,988 ft), almost in a straight line, including 525 metres (1,722 ft) of raised causeway. Its underground portion, and in particular its final journey, passes the hamlet of Villeronde.[1][2] Only a portion of the aqueduct-bridge is now visible as it passes through the "Valley of the Arennes".[3]
The actual channel for the water is masonry and not a lead or terracotta piping and has a slope of 1.5 cm to 2.9 m per kilometre. The maximum height of the arches of the aqueduct is 8.90 m.
