Château de Créminil was built in 1443 by La May family to the site of older fortification (destroyed by English Army). In 1540 Créminil was owned by Hugues de Buleux (advisor to the regent of the Netherlands and grand bailiff of Aire). After the castle was burned in 1543 it was rebuilt in the 17th century.
In 1670 it was owned by Antoine de Wignacourt and from 1687 till the Revolution by the Merchiers family. Until 1978 Créminil Castle was owned by a Mrs Lhéritier whose family had it since the Revolution.
This late medieval castle consists of an irregular polygon with twelve sides, built on a small mound surrounded by large round moat fed by water from the Laquet stream. In the 18th century 3 sides of polygon to the south were torn down and replaced by a terrace lined with stone balusters to provide a better view of the surrounding gardens. Also the facades of the buildings on the courtyard were rebuilt.
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.
