Eglise Saint-Pierre du Mont Saint-Michel, Catholic parish church in Le Mont-Saint-Michel, France

The Église Saint-Pierre du Mont-Saint-Michel is a granite parish church built against the east flank of the rock, halfway up the Grand'Rue. Its nave has a central vessel doubled by a south aisle, ending in a flat-chested chapel; the choir closes in a faceted apse. A square bell tower with a gabled slate roof stands against the south wall, and the church is bordered by the village cemetery.

Tradition attributes the church's founding to Saint Aubert, bishop of Avranches, in the 8th century; a charter of 1022 already names its dedication to Saint Peter, and Romanesque pilasters survive at the choir entrance. In the second half of the 15th century the transept chapels were rebuilt with flat chevets and a bell tower was added on the south side. The choir was extended with a polygonal apse around 1600, and on 4 November 1886 the church became the pilgrimage sanctuary of Saint Michael.

Since 4 November 1886 the parish church has also been a pilgrimage sanctuary, when the cult of Saint Michael was moved here from the abbey by the Bishop of Coutances. The church is dedicated to Saint Peter, named in a charter of 1022. In the Saint-Michel chapel stands a silver-leaf altar made in 1873 by Parisian goldsmith Jean-Alexandre Chertier, moved here in 1895.

The church sits halfway along the Grand'rue, pressed against the east flank of the rock, with the village cemetery bordering it to the south. Its overhanging main apse spans a narrow alley and forms a vaulted passage linking the building to the street. The ground floor of the bell tower, once open to the cemetery, now holds the Saint-Michel chapel, the only stone-vaulted chapel in the church.

The silver-leaf altar in the Saint-Michel chapel was made in 1873 by Parisian goldsmith Jean-Alexandre Chertier for the abbey church, then moved here in 1895 when the parish became the pilgrimage sanctuary. The chapel itself was the tower's ground floor, open to the cemetery until the late 19th century, and is the only stone-vaulted part of the church.
