Château de la Ville Der, Neoclassical château in Val d'Oust, France.

The Château de la Ville Der is a residence built in neoclassical style with symmetrical forms and balanced proportions that imitate ancient Greco-Roman architecture. This registered historical monument displays the characteristic features of this style in its overall composition and architectural details.

Architect Arthur Regnault designed this residence during a period when neoclassical style dominated French building practices. The structure emerged from an era marked by a shift away from baroque forms toward classical simplicity.

The estate's name shifted over time: the sources call it château de Ferrières, manoir de la Villeder or manoir de la Ville-Der, after the La Ville-Der hamlet. Ownership passed through the Guillard, Lézenet, Kermeno, Moro, du Lys, du Boisbaudry families, then the Hecht family from 1984. A private chapel dedicated to Saint Anne once stood here.

The château stands at La Ville-Der, about 1.5 km west of Roc-Saint-André, 2.4 km south of Quily and 4.4 km east-northeast of Lizio. Entry is from the east: a wrought-iron gate between two granite pillars on a bridge over the moat leads into the cour d'honneur. The building is inscribed as a monument historique since 4 June 2007.

The entrance gate rests on two granite pillars set on a bridge over the moat, and the château once had a private chapel dedicated to Saint Anne. The octagonal tower and the spiral staircase survive from the 15th-century building, before Arthur Regnault's 1896–1900 remodelling.
