The grey stone church of Hauho was built probably at the beginning of 16th century. The present sacristy made of bricks replaced the old medieval one 1783-1784. The bell tower was built in 1811. The church bells were moved over to the new church in 1885.
There are several medieval wooden statues in the church, for example St. Peter and St. Anna.
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.
