The town is the capital of the Haute-Savoie department, with a well preserved old-town along the banks of the river running out of the lake. We stopped for lunch at a terrace restaurant beside the river next to the 12th century Palais de l'Isle Jail (Palace of the Isle of the Jail) - one of the most photographed landmarks in France. After a pleasant steak we were entertained by a miming clown, who appeared wheeling a unicycle but sadly did not ride it. Then we walked along the river to the lake to the strains of an accordion player. It was like walking through all the French cliches rolled up together.
Palais de l'Isle Jail from behind - the famous view is from the other side, but you can see that picture all over the web (Google, or Wikipedia it) so this is my one.
