Château de Vaucluse was erected around 1030 and the current ruins date from the early 12th century. In the 14th century it was a summer residence of Cavaillon bishops. Perched high above the village, the ruins are a very pleasant place to stroll. From there, the view embraces an exceptional panorama of Fontaine de Vaucluse, the spring and a large part of the region.
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.
