Le Locle
The earliest traces of human settlements come from the end of the Mesolithic period (6000-5000 BC) in shelter in the Col des Roches. The site includes the oldest pottery found in the Canton of Neuchâtel, along with many tools, the molar of a mammoth and deer and wild boar bones. The shelter was discovered in 1926 by a customs official and was the first site of its kind studied in Switzerland.
