Lausanne in 3 days: the Swiss city on three hills above Lake Geneva where the IOC has chosen its home since 1915, where a night watchman has called the hours from the Gothic cathedral belfry every night since the 13th century, where 800-year-old terraced vineyards climb steep hillsides above the lake heated by three suns, and where Lord Byron wrote his most famous poem in a dungeon that still bears his carved signature.
