Origin of the name Lausanne

The name is of Celtic origin. It appears in the 2nd century in an inscription naming the "vikanor[um] Lousonnensium" (the inhabitants of the vicus of Lousonna), then around 280 as "lacu Lausonio", around 400 as "civitas Lausanna" and in 990 as "Losanna". It is generally linked to the Celtic "lausa" (flat stone) followed by the suffix "-onna", which is thought to have first designated a stream before being applied to the Roman settlement (etymology to be cross-checked). The old German name was "Losannen"; in Italian and Romansh the city is "Losanna".

Founding of Lausanne

Lausanne has no single founder. The Vidy site on the lakeshore and the hill of the Cité have been occupied since the Neolithic. In Roman times a vicus called Lousonna developed at Vidy from the middle of the 1st century, on the road linking Italy to the Rhine across the Swiss plateau. In late Antiquity settlement moved to the more defensible hill of the Cité, and at the end of the 6th century the bishop's seat moved there (it had previously been at Avenches). The medieval town then grew around the cathedral and the power of the bishops of Lausanne, lords of the town, with the episcopal Cité on one side and the lower town on the other, which were only united in 1481.
