The wooden church in Karunki was built in 1815-1817. The cruciform shape church is designed by A. W. Arppe. The bell tower was erected in 1815. The altarpiece was painted by J. Hedman in 1827. There are also a manse (1861) and couple of wooden outbuidings on the church site.
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.
