The Book of Llandaff refers to the existence of a church, or monastery, on this site in about 735. The existing St. Peter's Church, now substantially rendered and whitewashed, consists of a nave with a separate chancel, a vestry, a tower to the west, and north and south porches. The oldest parts of the building, including the herring-bone masonry in the north wall of the nave, may have an Anglo Saxon origin or, alternatively, date from the 12th century. The nave seems to have been lengthened during the 13th century, perhaps when the tower and chancel were built. A small window in the southwest corner dates from the early 14th century. The exposed Old Red Sandstone walling in the chancel dates from the 14th century; the chancel has a sanctuary window on each side, a priest's door, and an ancient stone bench outside. A royal coat of arms dated 1711 is painted on a board inside the church.
The north porch and vestry were added in 1824, and the whole church was restored in 1861–62. Inside the church are five stained glass windows.
The church is too low-lying to prevent winter floods from entering the building, and brass plates near the chancel arch record the heights of notable floods. A new balcony has been constructed at the back of the church so that perishable items can be kept above the floodline. This balcony is decorated with a beautiful oak screen. The church had a rectory, which was later known as Dixton Cottage.
References: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.
