# Twann-Tüscherz

Twann-Tüscherz or Douanne-Daucher in French is a municipality in the Biel/Bienne administrative district in the canton of Bern in Switzerland. On 1 January 2010 the municipalities of Tüscherz-Alfermée and Twann merged into the municipality of Twann-Tüscherz.

## History

Twann is first mentioned in 1185 as Duana and again in 1225 as Tuanna. Tüscherz is first mentioned around 1230 as Tusschiers and in 1267 as Tuschers while Alfermée was first mentioned in 1276 Alphermme.

### Twann

Just outside the Twann railway station is a large and well preserved Neolithic lakeside settlement. It was discovered in the mid 19th century and in 1974-76 about 10% of the total site was excavated. Almost 20 different village existed at the site between 3838 and 2976 BC. The longest a single village was inhabited was only 24 years. The small huts (7 m × 4 m [23 ft × 13 ft]) were only temporary and most had to be repaired after less than four years and replaced after sixteen. The huts stood in serried ranks either longitudinally or transversely oriented to the lake. The hut floors had a layer of peat to keep them dry and a clay hearth in the center. The residents used hoes, sticks and simple plows to raise grain which was eaten as a porridge or bread. They raised domestic cattle, sheep and goats constantly and hunted animals, mostly red deer, as needed. They often fished in the lake. They wore clothes made of woven flax and bark fibers. An incised ceramic vessel shows trade links to Valais and a rock crystal shows that they traded with other alpine villages. About half of their flint tools came from local flint sources, while the rest of the flint came from distant regions including, southern Germany, the southern Rhone Valley and Champagne. One copper knife blade was also discovered at the site.
The other prehistoric sites include a Roman cremation grave in Rogget, early medieval finds in Gaicht and a burial ground in Gauchete.
The settlement of Rogget northeast of Wingreis was first mentioned in 1235. During the 14th century it was abandoned, probably due to a massive rockslide.
During the Middle Ages Twann was the capital of the Herrschaft of the Lords of Twann. In 1250, however, their line died out and it was inherited by the Baron de Diesse. Shortly thereafter it went to the Vaumarcus family and then the Bolligen family. The Bolligens held Twann until 1422 when they sold it to the Bernese Schultheiss Rudolf Hofmeister. He established it as a Twingrecht or lower jurisdiction with a judge in 1426. Rights over parts of the village were held by a number of different nobles, but by 1470 the right to hold a court in Twann was split between Bern and the Prince-Bishopric of Basel.
The village church of St. Martin was first mentioned in 1228 and belonged to the diocese of Lausanne. The first church was built in the 9th or 10th century. This building was replaced in the 13th century and again in the 15th century. The current appearance of the church comes from Abraham Dünz the Elder's renovation in 1666-67. In 1237 Kuno von Twann gave the right to appoint the village priest to the Münchenbuchsee Commandery. During the Reformation, the Commandery was dissolved and in 1528 control over the church went to Bern.
The local economy was based on viticulture, fishing and animal husbandry. Weekly markets allowed the residents to buy any grain that they needed. Many of the vineyards were owned by Bernese nobles or by Engelberg Abbey, Münchenbuchsee Commandery and Fraubrunnen Abbey. After the Reformation, the monastery vineyards were acquired by Bern and leased out to local farmers. In Wingreis, the Rebhaus Thormanngut, a vineyard manor house, was built in the 16th century for Bernese patricians.
For most of the history of Twann, the main transportation mode was by ship. The first road that connected Twann to Biel was built in 1835-1838. About twenty years later it was followed by the Biel-Neuchatel railway line in 1858-1860. The expansion of the railway and the highway, in 1969-1978, separated the village completely from the lake. While viticulture is still important to the village, tourism, a shipyard and a construction company are also important parts of the local economy. In 1977-80 a vacation village was built on the Twannberg. It was sold and converted into a hotel in 2009.

### Tüscherz-Alfermée

Tüscherz and Alfermée were part of the lands of the Counts of Neuchatel-Nidau, until 1388 when the counts died out and the land was acquired by Bern. Originally it was part of the parish of Sutz which was located on the opposite side of the lake. The priest at Sutz allowed the Mass to be read in the chapel above Tüscherz. After the Protestant Reformation the chapel was closed, but it remained part of the Sutz parish until the parish was dissolved in 1876. Tüscherz and Alfermée then became part of the parish of Twann. In 2010 the parishes of Twann / Tüscherz-Alfermée and Ligerz merged to become the Pilgerweg Bielersee parish.
Viticulture and fishing dominated the villages, because there was little land for growing grain. Some of the residents even rented fields across the lake in Sutz. Many of the vineyards were owned by monasteries, hospitals and lower nobility or burghers of Bern, Biel and Nidau. Several vineyard estates were owned by St. Urban's Abbey, including the Schünen estate which was bought in 1256 and later abandoned and the Convalet estate which was owned by the Abbey until 1848. In the 18th century it was expanded into a large manor house but it was demolished in 1859. The Biel/Bienne road (built in 1838), the Biel/Bienne-Neuchatel railroad (built 1860) and the A5 motorway (1973) isolate the villages from the lake. The lower village of Alfermée was built on land won from the lake after the Jura water correction in 1868-91 but was demolished in 1969 to clear land for the motorway. Until 1973 the primary school was located in the municipality, then it relocated to Twann. The vineyards are still an important industry, though now about two-thirds of the working population commute to Biel/Bienne for work.

## World Heritage Site

It is home to the Twann Bahnhof prehistoric pile-dwelling (or stilt house) settlements that are part of the Prehistoric Pile dwellings around the Alps UNESCO World Heritage Site.
Twann Bahnhof is one of the best dated prehistoric lakeside settlements. The wooden piles have been dendrochronologically dated to 3838-3768 BC, 3702-3698 BC, 3662 BC, 3649-3631 BC, 3622-3607 BC, 3596-3573 BC, 3563-3532 BC, 3405-3391 BC, 3176-3166 BC and 3093-3074 BC. The site was discovered in the mid-1870s during digging of a well. One large scale excavation was carried out in 1974-76, while test borings in 1984-87 indicated that some of the archeological layers extend far into the lake. The total site is estimated to cover 12,000 square meters (130,000 sq ft), but only 1,200 square meters (13,000 sq ft) were excavated in 1974-76. The underwater portion of the site has not been explored. A few years after the excavation the results of the studies were published in a 20 volume collection, which is considered the definitive reference on the Neolithic development in western Switzerland.
