In 590 St. Leonhard, a disciple of Columbanus, founded a benedictine monastery which later was named after the abbot Maurus who modified it in the 12th century imitating the style of Hirsau. The church dates from this time. Above all the cloister flourished during the 14th century. In 1792 it disintegrated during the French Revolution.

Jacob Frey, a writer, lived in Marmoutier from 1545 as town chronicler and notary.

The church of Marmoutier Abbey from the 11th century holds a pipe organ by the organ builder Andreas Silbermann. Église Saint-Blaise de Sindelsberg was built in 1584 and underwent renovation work in 1872.
