The old hill town on the edge of two lakes (watersports) is now part of Turin’s stockbroker belt. Towers, arcades, medieval houses and a ruined 17thC castle survive, but the main attraction is the nearby Sacra di San Michele. The 10thC fortified abbey clings to a rock 500 m up, guarding the approach to the Susa Valley. Note the frescos, carvings and, on the Scalone dei Morti (‘stair of the dead’), the zodiac door. The wide-ranging views from the terrace are a bonus.
