The current structure of Chiesa Parrocchiale di Saint-Vincent, with a large circular apse, dates back to the 15th century, when important changes were made to a probable, pre-existing Romanesque building. For some time it conserved certain parish church prerogatives (festive functions and cemetery), even though it was never a parish church.The apse vault has a beautiful series of ribbed stone. Recent restoration removed the modern structures and decor, in an attempt to restore the church to its original appearance. In the past, on Easter Monday, the so-called “vineyard procession” took place, which in almost six hours passed through all the villages and chapels on the Saint-Vincent hillside.
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.
