Château de la Cassine, Château ruin in Vendresse, France

Château de la Cassine is a ruined stone complex in Vendresse, with low ivy-covered walls on the left and a taller pale grey-beige tower-like fragment on the right, featuring an arched opening at its base and a squared upper portion. Lower broken walls, some patched with brick, stand between them in a grassy field backed by trees.

Louis IV of Nevers built the château in 1571. The ironmaster Jean-Nicolas Gendarme bought it in 1820, and his heirs, the Camion family, rebuilt it in the 19th century; it passed by marriage to the Cunin-Gridaine family. A fire ravaged it in 1927 and it was never restored.

The ruined château hosts a sound-and-light show staged among its walls, drawing on the site's history. The performance is the main way the former residence is used today, after the 1927 fire ended its life as a home.

The site can be explored on foot, allowing visitors to view the ruins from multiple angles. Visiting during daylight hours and clear weather provides the best view of the stone structures.

The painter Paul de Lapparent (1869–1946), a descendant of Jean-Nicolas Gendarme who bought the estate in 1820, frequented the château. The Camion family, Gendarme's heirs, rebuilt it in the 19th century before it passed by marriage to the Cunin-Gridaine family.
