Château du Tertre

Château du Tertre is a 17th-century castle in the Louis XIII style, built on elevated ground with a central structure topped by slate roofs. A formal French garden surrounds the main building and frames views toward Bellême forest.

The castle was built by historian Bry de la Clergerie and later expanded under Napoleon I's minister Abrial. These two influential figures shaped the structure as it developed over different periods.

The castle holds the Maisons des Illustres label and preserves the study and library of writer Roger Martin du Gard. Today it serves as a working space where artists and writers create and share their work.

The castle opens seasonally, primarily during warmer months, and visitors should check in advance whether interior tours are needed or recommended. Its location on elevated ground makes it easily accessible for those interested in exploring the architecture and gardens.

The castle hosts artist residencies where creative professionals are invited to work and create during their stay on the grounds. In addition, theater performances and music concerts are held regularly, keeping the property active as a cultural venue.
