Douanne, or Twann in German, is a charming wine-growing village nestled among the vineyards on the shores of Lake Biel. Take the time to explore the cobbled streets, sample fresh lake fish, and soak up the village's Mediterranean atmosphere.

The wine-growing village of Twann stretches along the lake from the Twannbach (border with Ligerz) through Klein-Twann, the village center of Twann with the church, the Moos, the hamlet of Wingreis to the Fluhbach (border with Tüscherz). Towards Jura, the village stretches over the farming hamlet of Gaicht to the Twannberg. The St. Peter's Island also belongs to Twann. Excavations have shown the remains of a Neolithic lakeside settlement in the 4th/3rd millennium BC. The village name can be traced back to the Celtic period around 400-500 BC. The church dates from the early Middle Ages (9th century). In the 12th to 13th centuries, the name Tuana was first mentioned in a document confirming the transfer of an estate to Baron Berchtold von Twann. With Cuno von Twann, the Baronial family of Twann died out. This was followed by the Twing rule (noble rule) in the 15th to 18th centuries. Source https://bielersee-tourismus.ch/twann/
