Hansli Kopp discovers La Tène artifacts at Lake Neuchâtel

Background. Lake Neuchâtel, located primarily in the French-speaking part of Switzerland, was frequented by prehistoric populations. The lake's water level dropped significantly in 1857 due to prolonged drought and the Jura water correction, exposing previously submerged areas. This environmental change coincided with a period known as the 'lake dwelling fever,' which drove increased archaeological exploration of prehistoric sites in the region.

Discovery. In November 1857, fisherman Hansli Kopp, acting on orders from Colonel Friedrich Schwab, spotted an interesting spot near La Tène while sailing to a Neolithic dwelling near Concise. This observation led to the recognition of the site as a significant archaeological location. The site is situated on the northern shore of Lake Neuchâtel, where the Thielle river enters the lake.

Significance. The La Tène site became the type site for the La Tène culture, dating to the second part of the European Iron Age. Thousands of objects were found deposited in the lake, including weapons, tools, and coinage. These findings established the cultural framework for a widespread Celtic world that extended from Ireland to Asia Minor.
