Upstream of the village of Bursins, in the heart of the La Côte region, exactly between Geneva and Lausanne, the Château Le Rosey estate is overlooked by four and a half hectares of vines extending on a gentle slope towards the first wooded foothills of the Jura and worked biodynamically. Probably built at the beginning of the 13th century in the form of a Savoyard square, partly burnt down, damaged by wars, transformed, enlarged, the castle underwent multiple transformations over the centuries, until its last restoration. Today, with its orchard and vegetable garden, it has regained its medieval vocation as a refuge, haven and stopover, taking the name Relais Viticole.

The ruins of the Charterhouse of Oujon are in the middle of the forest. A Charterhouse (Chartreuse in French) is a monastery belonging to the Carthusian Order. It was built around 1146 and is the oldest of its kind in Switzerland. The cellar walls of the various buildings are still visible today, so that you can get a good idea of the size of the former monastery.
