Château de la Prune-au-Pot, Medieval castle in Ceaulmont, France.

The Château de la Prune-au-Pot is a medieval fortress in Ceaulmont featuring defensive walls with machicolations, a central square tower, and two round towers surrounding an inner courtyard. The arrangement creates a compact and well-fortified structure.

The castle takes part of its name from the Pot family, its owners for a long period; one branch of the family also bore the name. The Pots abandoned it in the 15th century, after which it stood uninhabited and in ruins. In 1532 François de Montmorency, ordinary chamberlain of the King and his lieutenant general in Picardy, was lord of La Prune-au-Pot. In the 17th century the lordship passed to the Bourbons and then entered the royal domain; the land was sequestrated after the Revolution.

The rooms inside show French medieval craftsmanship through their large fireplaces and spiral staircases that remain visible today. Visitors can see how daily life and comfort were designed into these spaces.

The castle stands in a meadow on a slope above the Creuse, and visits are possible in season only from outside the enclosure, as the ruins are not entered. The site is reached from Ceaulmont in the Creuse department; the grounds are uneven and unrestored.

The castle was abandoned by the Pot family around the 15th century and has stood uninhabited and in ruins since then. Volunteers from the association Chantiers Histoire et Architecture Médiévales carried out maintenance work between 1985 and 1996, and the Aguttes family, which bought it in 2000, began restoring it.
