Overview
Mont-Saint-Michel rises from a granite outcrop in the Couesnon estuary between Normandy and Brittany, France. According to legend the archangel Michael appeared to Bishop Aubert of Avranches in the 8th century; an oratory was established by the 9th century, and the Benedictine abbey developed from the 10th century under ducal and royal patronage. The Gothic choir of the abbey church ("La Merveille") was built from 1211–1228 on the steep slope in three stacked levels — crypts, cloister, and refectory — a feat of medieval engineering.
The mount functioned as a fortress during the Hundred Years' War (never captured) and as a prison after the Revolution until 1863. A causeway built in 1879 altered tidal dynamics until a 21st-century bridge and dam project restored partial maritime character. The village within the walls retains medieval street pattern and pilgrimage infrastructure.
UNESCO listed Mont-Saint-Michel and its Bay in 1979. It ranks among the top visitor attractions in France alongside the Eiffel Tower and Palace of Versailles.
