Les Chatelliers and Châteaumur are two ancient villages which once looked at each other on its own hill. They were united in 1825 to form the commune of Châtelliers-Châteaumur, itself recently integrated into a community of communes.
Raised on a feudal motte, the keep is accessible by a carriage gate, originally defended by a drawbridge. It is surrounded by houses which mark the enclosure of the disappeared castle.
Established on a small hill bordered by a pond, the magnificent Domaine de la Roche dates from the end of the 19th century. Now owned by the city, it houses a group accommodation centre.
