2 Best Sights in Viviers, Lyon and the Alps

Situated in the old religious quarter high over the town, this 14th-century fortification (built in 1359) provides an exceptional 360-degree panorama over the port, the river, Vivier's rooftops, and the Rhone Valley.

This exceptional example of a Roman bridge, built over the Escoutay River, is well worth the mile walk from the town center. Typical of the second century Roman style, with central portions dating from the second or third century, the bridge was reinforced in medieval times. The 330-foot long structure retains 11 of its original 12 or 13 arches and was part of a Roman road built to carry wine and salt through the region. For intrepid sightseers, the Chapelle Saint-Ostian is about a half-mile up the road.
