Although I have never stayed at this hotel, I have toured it inside and out for its historical and architectural value. Even if you are not staying overnight, it is worth going to have a walk around the building
Built in 1892 on the site of Château St.-Louis (1647) to resemble an European castle, Château Frontenac is one of Québec City’s best-known and most visible landmarks. Dominating Place d’Armes, a large square in Upper Town used for military drills and parades during the French regime, this majestic sentinel overlooking the St. Lawrence River, 100 meters below, has hosted kings, queens, and heads of state.
