Château de Maillebois, Renaissance castle in Maillebois, France.

Château de Maillebois is a red-brick castle with a dark slate roof, standing across a grassy field beside a body of water and trees. A round tower with a conical roof and small lantern rises at its left side, and a smaller round tower with a similar roof closes the right end. Between them, the long facade has stone-framed windows and a section of diamond-patterned brickwork.

The original medieval structure was burned by the English in 1425 and subsequently rebuilt. It later became a residence for François d'O, who served as finance minister under King Henri III.

The château gave its name to the marquisate created by letters patent in 1621 for Anne Le Camus de Jambville, dame d'honneur to Catherine de Médicis and Anne d'Autriche. She died in 1651 in her Paris townhouse but was buried in the parish church of Maillebois. The village itself was moved to another spot by Nicolas Desmarets to enlarge his park.

The castle stands in the commune of Maillebois, in the Thymerais, north of Eure-et-Loir; the water and trees seen in the photograph border its left side. The facades and roofs of the château were listed as a monument historique on 22 December 1941, the outbuildings in 1974 and the stables in 2000. The sources give no opening times or tour arrangements, so check locally before travelling.

The château was inscribed as a monument historique on 22 December 1941; the facades and roofs of the outbuildings followed in 1974, and the entire stables in 2000. Since the Revolution, the estate has belonged to only two families.
