"The Pont du Gard (Roman Aqueduct), in France, was built shortly before the Christian era to allow the aqueduct of Nîmes (which is almost 50km long) to cross the Gard river. The Roman architects and hydraulic engineers who designed this bridge, which stands almost 50m high and is on three levels, created a technical as well as an artistic masterpiece. (via Imapix)
