Castle of the Châtelard, Medieval fortified house in Yenne, France

The Château du Châtelard is a ruined 14th-century fortified house on a knoll above the Yenne valley, 2.8 km south-southeast of the town near the hamlet of Châtelard. By the early 20th century only a few stretches of wall remained. It is not the nearby Maison Forte du Châtelard, birthplace of actor Charles Dullin, a few hundred metres to the south.

The stronghold belonged to the Chevelu family in the 14th century, with Galois de Chevelu formally acknowledging his control to Duke Amédée VIII in 1408. A fortification agreement from 1441 later formalized its role as a guarded defensive position.

The name derives from castellarium, Latin for a fortified house, rendered in local records as Chastellard. The site was the seat of the seigneurie du Châtelard, and in 1441 Claude de Seyssel agreed with the syndics and inhabitants of Yenne over the watch, guard and fortification of the house, with armed men of the parish of Chevelu keeping guard there on Saint Bartholomew's Day, 24 August.

The ruins stand on a knoll 2.8 km south-southeast of Yenne's town centre, near the hamlet of Châtelard. Only a few stretches of wall remained by the early 20th century, so the remains are fragmentary. Do not confuse the site with the second Châtelard fortified house a few hundred metres south, the birthplace of actor Charles Dullin.

The 1839 inheritance concerns the second Châtelard house, a few hundred metres south of these ruins, not the ruins themselves: General-Comte Joseph de Cordon died childless and left it to his friend Joseph Dullin, a tax collector in Yenne. Dullin's nephew Jacques then lived there and raised eighteen children, the youngest being the actor Charles Dullin.
