Altnußberg castle was built by the Counts of Bogen probably between 1174-1194. During the so-called Böckler warin 1468-1469 the castle was burned down and razed. Today the castle is excavated and reconstructed partially. Guided tours through the castle grounds and the attached castle museum are available in summer season.
Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
A pleasant 30 minute-walk through the vineyards between Vufflens-le-Château and Denens, offers a stunning view of this magnificent castle, the lake and the Mont-Blanc.
