The abbey Saint-Chef develops over time. The abbey church dates from the 10th and 11th centuries. A first castle is built on the north hill. It will be followed by two others, later, still on the same hill but further west. After the
French Revolution, the abbey was dismantled and its buildings re-used for the most part, or destroyed for some others. Between 1790 and 1794, Saint-Chef absorbed the communes of
Arcisses, Chamont, Crucilleux,
Laval-de-Saint-Chef,
Montcarra, Trieux and
Vercin. The current mayor is Alexandre Drogoz who replaced Noël Rolland in 2020.
Abbey of Saint-Chef This abbey was founded around the year 500. The 12th and 13th century Saint-Theudère church, with its flamboyant Gothic portal and its organ, was listed as a historic monument in 1840 by Prosper Mérimée. The main building houses one of the most important sets of Romanesque frescoes in France dating from the twelfth century, on the theme of the Apocalypse, also classified as a historic monument. The historical and artistic interest of its frescoes has earned them reproductions in the

Saint-Barthélémy de Chamont church Located three kilometers from the main body of the village, in the hamlet of Chamont, this church was erected in 1879. In 1982, it became disused but, in 2001, an association close to the Lyon priory of the Priestly Fraternity of Saint-Pie-X bought building. Since then, it has been served by its priests officiating there according to the Tridentine form of the Roman rite. ==Population==
