Valga is first mentioned as a meeting point of tradesmen in the Riga Credit Book of 1286, but it got its city rights only in 1584 from the king of Poland, Stefan (István) Bathory, who was originally Hungarian. To commemorate this, a monument to Stefan Bathory was opened opposite St John's church in the centre of the town in 2003.
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.
