There are chalybeate springs close to the town. Château-Gontier owes its origin and its name to a castle erected in the first half of the 11th century by Gunther, the steward of Fulk Nerra of Anjou, on the site of a farm belonging to the monks of St Aubin d’Angers. On the extinction of the family, the lordship was assigned by Louis XI of France to Philippe de Comines. The town suffered severely during the wars of the League. In 1793 it was occupied by the Vendeans.
