St. Peter's Church have been probably built in two phases during the 12th century.The eastern part with chancel, transept and central tower were erected first during the late 1100's, while the nave and the present west tower were added later.
According the tradition the church was used as a bishop’s cathedral until 1130 when the bishop's seat was moved to Gamla Uppsala. The another legend believes the church has been a royal church. After a fire in the 1600s, the church has stood as a ruin.
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.
