Perhaps one of the most remarkable sights in France, a chapel perched on a volcanic plug. This is the Rock of Aiguilhe, on the edge of the town of Puy en Velay, in the Auvergne. The Chapelle Saint-Michel has stood there for 1042 years, since Bishop Gothescalk had it built in 962 on his return from a pilgrimage to Santiago del Compostella in Galicia. In 1955 workers found relics under the alter that had been there since it was built.
Mont Saint-Michel, a tiny (population: 44!) rocky island in the Normandy region of France. Although I'm glad I visited, I do regret eating the "famous" but overpriced and underwhelming omelets found here. There was construction when I visited (in May 2013) to add another paved lane of traffic going to and from the island.
