The first settlements date from 1500 BC. In the 5th century BC, the Celts settled in the alpine valleys among the sources of the Rhone, the Rhine and the Danube, eventually stretching from the headwaters down to Vienna and Belgrade. At the end of 1st century BC the Romans conquered this area. The Roman settlements were destroyed by the Alamanni in 259/60. They eventually settled in the area around 450. In any case, evidence has been found for a settlement by the Alamanni in the 7th century. Brienz is first mentioned in 1146 as Briens. In 1528, after an eventful history, Brienz became part of the Canton of Bern
