Resting under the wooden planks of the Dufferin Terrace in Quebec City are the ruins of the Saint-Louis Forts and Chateaux, now a national park. Despite having been the seat of the governor of New France as early as 1620, it wasn’t designated as a National Historic Site until 2002 and parts of the structure were not uncovered until 2007.

Over the years, three chateaux were built on the site. The first was built in 1648 but fell into disrepair later that century. A second was built in the late 17th century with sections added on in the early 18th century to create more space. The second chateau was damaged during the British invasion of Quebec, so a third was built, which was destroyed by a fire in 1834.

The kitchen, dining hall, ice house, and courtyard are visible on the site as are over a hundred historical artefacts. The third chateau even used some parts of the first chateau in its structure, so it was difficult to determine which part of the ruins were built during what time period.
Today, the nearest thing to a castle on the site is the Chateau Frontenac, home to the Fairmont Hotel in Quebec. It was built in 1893 as one of Canada’s great railway hotels.
