Champoz () is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland. It is located in the French-speaking part of the canton in the Jura mountains. History Champoz was first mentioned in 1365 as Champo. The Roman army built an observation post on the mountainside near the present day village. Very little is known about the early history of the village, but throughout its history it was owned by the bailiff of Malleray who was under the authority of the provost of Moutier-Grandval Abbey. In 1499, during the Swabian War, Imperial troops destroyed the village. Both before and after the Protestant Reformation in 1531 it was part of the parish of Chalières. This changed in 1746 when it became part of the Bévilard parish. After the 1797 French victory and the Treaty of Campo Formio, Champoz became part of the French Département of Mont-Terrible. Three years later, in 1800 it became part of the Département of Haut-Rhin. After Napoleon's defeat and the Congress of Vienna, Champoz was assigned to the Canton of Bern in 1815. The village is located in the mountains above the Tavannes valley. Because of its location, during the 19th century the roads, railroads and industrialization of the valley bypassed Champoz. Today, many residents still work in agriculture while others commute to jobs in the Tavannes valley. Geography Champoz has an area of .
