The seven-span Pont Valentré, on the western side of the city, south of the train station, is one of France’s most iconic medieval bridges, built as part of the town’s defences in the 14th century. The parapets projecting from two of its three tall towers were designed to allow defenders to drop missiles on attackers below. On the bank opposite the bridge, the Fontaine des Chartreux , dedicated to the city’s Gallo-Roman goddess Divona, was what the city was originally built around, and still supplies the drinking water.
