Château du Crest, Medieval wine castle in Jussy, Switzerland.

Château du Crest stands in Jussy, Geneva, on the site of a fortified house built around 1220 with moats, a drawbridge and crenellated walls pierced with loopholes. Rebuilt from 1621 by Agrippa d'Aubigné as a manor with turrets, loopholes, a drawbridge and a deep moat, it gained a square tower on its east side in the 19th century. The estate covers 8.5 hectares of vineyard and 250 hectares of farmland.

The first fortified house was built around 1220 for a vassal of the Bishop of Geneva, protected by moats, a drawbridge and crenellated walls. In 1590 Geneva troops took and destroyed it during the war with Savoy. Agrippa d'Aubigné bought the ruins and in 1621 obtained permission to rebuild, adding turrets, loopholes, a drawbridge and a deep moat.

Today the castle functions as a working vineyard producing wines under the Geneva AOC designation, a craft passed down through generations of the Micheli family. Visitors can see how the production and cellar work connect to the living history of the estate.

The castle opens for events where visitors can taste the estate's wines and tour the cellars. It is best to check in advance for open dates, as visits are tied to specific events.

The square tower on the east side was added in the 19th century by the botanist Marc Micheli, who grew rare plants on the estate. The barns and stables, ravaged by a fire in 1989, were rebuilt by Yves Micheli in 1991. The foundation today holds 8.5 hectares of vineyard and 250 hectares of farmland.
