This is a three-story stone arch bridge with more than 2,000 years of history. In fact, it is a high-altitude water diversion aqueduct built during the ancient Roman Empire. This Galle bridge in southern France is as spectacular as the sink in Segovia, Spain! The bridge, which spans the Nar River, was originally built to bring water to the small town of Nim and then to public baths, fountains and private homes. If the bridge is viewed from the perspective of ancient Roman architecture, it should be the most important contribution of the ancient Romans to the construction of human civilization and living facilities.
