The residents of Saint-Nicolas de Ver, possibly an unsuccessful town founded by the Lords de Mont, settled in Rolle. The new city, which was built with a palisade, was granted a city charter along the lines of the charter of Moudon. As compensation, Jean de Mont became a deputy ruler and received a dairy farm and half of the furnaces and mills. Starting in 1366, the citizens became exempt from tolls in Aubonne. The Duke of Savoy granted the right to hold a weekly market in 1425. In 1484, he elevated it from a feudal property to a free city.
