Skalunda Church might be built in the late 100s or around 1140. It is anyway one of the oldest in the region. The sandstone church has Anglo-Saxon features, and it is possible that it was built by unkown English or Norwegian missionaries. The porch and sacristy were added in the 15th century as well as vaults. The belfry dates from 1772. There are also two runestones in the churchyard.
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.
