One of Québec City's most famous landmarks, this historic building and hotel has hosted many notables, including Grace Kelly, Alfred Hitchcock, Prince Rainier, Winston Churchill and Franklin D. Roosevelt. In fact, several summit meetings between Churchill and Roosevelt were held here, resulting in strategies that helped the Allies win World War II. The 1908 castle-like structure can best be viewed from atop the Citadelle or the Levis Terrace. Worthwhile guided tours are available, led by guides dressed in period attire.
