Château d'Haroué was built between 1720 and 1732 by Germain Boffrand during the period when Lorraine was independent of France, for Marc de Beauvau, prince de Craon, viceroy of Tuscany and constable of Lorraine.
Surprisingly, the architect had to integrate into his plans the four towers and moat of an older medieval château, a consideration for medieval buildings which was unusual for the classicist period. Le château's design also symbolises a year: 365 windows, 52 fireplaces, 12 towers (several included in the buildings) and 4 bridges crossing the moat.
The decoration was largely entrusted to artists from Lorraine : Jean Lamour (1698–1771) for the gates, balconies and staircases, Pillement (1698–1771) for the painted decoration of one of the towers, Barthélemy Guibal (1699–1757), sculptor of the fountains of place Stanislas at Nancy, for the statuary. The park was designed by Emilio Terry.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
