In 1261, the Lords of Mont planned to build a city along the lake that would compete with the Aubonne and Saint-Prex. By around 1264, Rolle Castle was built to protect the pier at the lake. However, the planned city was never built by the Mont family. In 1291, the castle was in possession of Count Amadeus V of Savoy, who granted it to several different families as a fief. In 1295 it passed to the Knight Jean De Grailly the 1st who named it Ruello changed centuries later to Rolle. In the course of the rivalry between the Counts of Savoy and the Lords of Vaud, in 1319 Amadeus V of Savoy finally built a city around the castle. This new city closed a gap in the savoy settlements on the northern shores of Lake Geneva. The layout of the town, a large main street running parallel to the lake shore with a cross street the connects the port with the hinterland, follow the construction patterns of typical Zähringer towns.
