Opened in 1893, the Châteauesque-styled building has 18 floors; its 79.9-meter height is augmented by the 54 m elevation it sits at. It is one of the first completed grand railway hotels, and was designated a National Historic Site of Canada in 1981. The hotel was expanded on three occasions, with the last major expansion taking place in 1993.

To the northeast of the hotel lies the Ursulines Monastery of Quebec, a 17th-century monastery founded by a missionary group of Ursuline nuns, and another National Historic Site of Canada. To the south of the hotel lies the Plains of Abraham, a historic area within The Battlefields Park, and the site of the Battle of the Plains of Abraham. Another major attraction south of the hotel is the Citadelle of Quebec, situated at the atop Cap Diamant, an elevated point of the promontory. The Citadelle serves as an active military installation for the Canadian Armed Forces, as well as a secondary official residence for the Canadian monarch and the Governor General of Canada. East of the hotel lies the Terrasse Dufferin, and Old Quebec’s Lower Town directly below it.

Access to the hotel’s main entrance is marked by several porte-cochère with large dormers and a cupola. The porte-cochère leads guests into the hotel’s center courtyard, as well as the entrance to the hotel’s main lobby. The building stands 80-meter-tall, containing 18 floors primarily made up of guest rooms and other hotel amenities. After the addition of the tallest tower in 1924, the hotel became the tallest building in Quebec City. It remained the city’s tallest building until 1930, when Édifice Price was completed just northwest of the hotel. Although several buildings in Quebec City are taller, the hotel continues to hold a prominent position in the city’s skyline, as it is perched atop a tall cape overlooking the Saint Lawrence River.

The Château Frontenac includes 610 guest rooms and suites spread throughout the hotel building. Eight executive suites were renovated into specialty “themed rooms”. Most of the suites are themed to the heads of state and government that have visited the hotel, such as the Trudeau-Trudeau Suite, named after two Canadian Prime Ministers, Pierre Elliott Trudeau, and Justin Trudeau. The Churchill Suite and Roosevelt Suite are two suites named after attendees of the First and Second Quebec Conferences, British Prime Minister Winston Churchill and American President Franklin D. Roosevelt, respectively. Other suites themed in honour of world leaders include the Charles de Gaulle, named after the former President of France, and the Elizabeth II, named for the Queen of Canada. A number of rooms at the Château Frontenac are also occupied by restaurants and other food-based services.

Fairmont Le Château Frontenac has since emerged as one of the world’s preeminent holiday destinations. Countless international luminaries have stayed at this spectacular hotel over the years, including military aviator Charles Lindberg, Princess Grace Kelly of Monaco, and French President Charles de Gaulle. Even Queen Elizabeth II of the United Kingdom visited the Fairmont Le Château Frontenac in the past.
