# Mühleberg

Mühleberg is a municipality in the Bern-Mittelland administrative district in the canton of Bern in Switzerland.

## History

Mühleberg is first mentioned in 1011–16 as Mulinberg.
There are several Hallstatt era grave mounds around Mühleberg; the most important is the so-called Unghürhubel (monster hill). At Unghürhubel in 1869, an ornamented choker made of heavy gold plate and a gold bracelet or strip with four rows with half-moon shapes were discovered. A number of other less valuable artifacts and metal items were probably destroyed during the excavation.
The church and village of Mühleberg belonged to a cadet branch of the von Buch family starting in 1387. It was then owned by the Brüggler family (starting in 1440) and the Herren family (in 1579), who sold it to Bern in 1599. It was combined with several other small estates and placed under the bailiwick of Laupen.
St. Martin's Church was first mentioned in 1224, though it was originally a romanesque aisleless church from the 11th century. The church tower was from the 12th century. It was expanded in 1523–24 with a new choir and became the parish church of a large parish. After the Protestant Reformation, the parish included Frauenkappelen.
The hydroelectric plant was built in 1917–21, which created Lake Wohlen. The Mühleberg Nuclear Power Plant was built in 1967–71. Both plants provide power to Bern. Following the Chernobyl disaster, public opinion swung against the power plant. In 1992, a public referendum in the canton of Bern rejected granting an unlimited operating license to the power plant, with 51% voting against. In 2003, 68% of the population rejected the initiative named Strom ohne Atom, that proposed that the plant should be shut down in 2005 to be replaced by non-nuclear power generation. A similar proposal at cantonal level had already been rejected in 2000 by 64% of voters. The two power plants remain the largest employers in the municipality.

### Gümmenen

Gümmenen was the site of a medieval castle and village on the banks of the Saane river. It was first mentioned in 1252 as Guminun and in 1259 it was called, in Latin, Contamina or Condamina.
Gümmenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zähringen as part of the defenses along the Saane, along with Laupen Castle and Grasburg Castle. The castle was built to defend a bridge over the river. By 1391, a village (villa inferiori Dicti castri) had developed around the bridge. In 1259, Peter of Savoy made Gümmenen into an imperial fief and imperial castellans took over the castle and village. In 1282–83 King Rudolph I of Germany forced the Savoy castellan out and granted it to a Habsburg knight, Ulrich II of Maggenberg as a fief. Ulrich's heirs sold the castle, ferry and ford to Fribourg in 1319. Fribourg then granted the lands to the knights of Vuippens, who lost it back to either the Holy Roman Empire or Fribourg in 1325. The castle and village were besieged and destroyed in 1333 during Bern and Fribourg's first war over the Sense and Saane valleys, the Gümmenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gümmenen to Fribourg.
Fribourg granted Gümmenen to one of their citizens, but in 1389, Bern acquired the usufruct right to Gümmenen. Then, during the 1447–48 Freiburg War Bern established a Bernese court in Gümmenen. Bern received the rights to the village in the peace treaty that ended the war. Around 1450, they built the first wooden bridge over the river. In 1454, Bern gave the village back to Fribourg, but in 1467 the Bern-Fribourg border was fixed on the right bank of the Saane river and Gümmenen was assigned back to Bern.
The current old village was built during the 17th and 18th centuries. The current wooden bridge was built in 1732–39. The village developed as a small border crossing. It had two taverns, a forge and a customs and guard house at the wooden bridge. It remained a customs and guard station until 1853, when internal tolls were abolished in the new Swiss federal state.
