Mont-Saint-Michel
design, history & builders

Mont-Saint-Michel is a rocky tidal island off Normandy crowned by a Benedictine abbey. Bishop Aubert founded a chapel there in 708; monks built a Romanesque church on the summit from 1023 and the Gothic 'Merveille' on its north flank in 1211–1228. A causeway built in 1879 silted up the bay, so it was replaced with a bridge in 2014, letting the tides surround the Mont again.

Mont-Saint-Michel: what it is

The Mont rises about 80 metres from tidal flats at the mouth of the Couesnon river, where tides are among the strongest in Europe. Pilgrims crossed the sands at low tide to reach the shrine of the Archangel Michael.

During the Hundred Years' War the fortified Mont never fell to the English. After the Revolution the abbey became a prison until 1863, and was restored as a monument from 1874.

Mont-Saint-Michel: how it was designed

  • 01

    A church on a pyramid of crypts

    The summit was too small for a large church, so builders created a platform of crypts and walls around the peak, and set the abbey church on top.

  • 02

    The Merveille

    On the steep north side, three storeys of Gothic halls stack one above another — almonry and storeroom, then guest hall and knights' hall, then refectory and cloister — a feat of building on a slope.

  • 03

    A town that spirals up

    The village winds up the rock inside ramparts, so the whole Mont reads as a single pyramid from the base to the gilded statue of St Michael.

Construction timeline

  1. Bishop Aubert of Avranches builds an oratory after visions of the Archangel Michael.

  2. Benedictine monks settle on the Mont.

  3. A Romanesque abbey church is built on the summit.

  4. The Gothic Merveille is built on the north side.

  5. The Romanesque choir, collapsed in 1421, is rebuilt in Flamboyant Gothic style.

  6. A neo-Gothic spire with Emmanuel Frémiet's gilded statue of St Michael is added.

  7. A light bridge replaces the 1879 causeway; a dam on the Couesnon flushes silt from the bay.

How the design changed

Two churches in one

The abbey church has a Romanesque nave and a later Gothic choir, so its two halves show four centuries of change in a single building.

Island lost and regained

The 1879 causeway let sediment build up and threatened to join the Mont to the mainland. The project completed in 2015 restored the tidal flow so it is again surrounded by water at high spring tides.

Who built it

Bishop Aubert founded the sanctuary; Benedictine abbots led the medieval building campaigns, supported by the dukes of Normandy and the French crown. The 19th-century restoration was led by architects including Édouard Corroyer and Victor Petitgrand.
