You may see Vienne Cathedral in the skyline before you actually find this important religious building. Take a seat inside if the doors are open or just admire the facade from outside.
Vienne Cathedral is a great place to begin your discovery of Vienne. This principal church comes recommended by fellow travelers, but it's not the only spot to see here. Pencil in time for other sights like Theatre Antique, Temple d'Auguste et de Livie, and Gallo-Roman Museum of Saint-Romain-en-Gal to fully appreciate what's on offer in the area.
