Ruppoldingen
Ruppoldingen is the name of a narrow step in the terrain between the steep southern slope of the Born and the Aare in the southern section of the municipality of the city of Olten in the Swiss canton of Solothurn .
history
A restaurant had existed in the agricultural settlement on the road from Aarburg to Boningen since the 19th century .
Around 1894, the place name became internationally known with the construction of the first large hydroelectric power station on the Aare, the Ruppoldingen power station . In 1904, this was even expanded to include the first small pumped storage power plant in Switzerland. This included an upper water basin built on the nearby Born mountain .
Today, the new Ruppoldingen power station, located in the municipality of Boningen, serves as a replacement for the original power station . The plant built around 2000 is a modern run-of- river power plant .
The joint stretch of the two main motorways in Switzerland, the A1 and A2 , runs in the section between the Wiggertal and Härkingen branching structures through the Ruppoldingen area and crosses the Aare here.
Origin of name
The field name with the ending in -ingen testifies to the emergence of a village settlement in the Middle Ages at this point, where, however, there has only been a simple farm for centuries. The former village must have lost its function in the late Middle Ages, while its name still remained. It is unclear at what point in time the village area was added to the territory of the city of Olten.
