CULLY, SWITZERLAND.- In 1946 Marcel Duchamp spent five weeks in Switzerland, five days of which, from 5 to 9 August, at Lake Geneva with one of his lovers, Mary Reynolds. He took up residence at the Bellevue Hotel (today, Le Baron Tavernier) in Bellevue near Chexbres. The hotel is located in the very heart of the Lavaux vineyards which have been designated a world heritage site by UNESCO. The hotel on the Route Corniche offers the most striking panoramas in the region with a magnificent view of the lake flanked in the background by the mountains of Vaud, Valais and Savoy and the entire chain of the Jura range. On clear days one can see practically the entire lake from Villeneuve to Geneva, as if it were a vast bay. The Corniche runs through the extraordinary vineyards of the region, linking Chexbres with the villages of Epesses, Riex and Cully. The Bellevue Hotel
