The Church of St. Catherine in Nummi suburb represents the medieval church building tradition. The construction began in the 1340s, the sacristy was completed first and the church later. Bishop Hemming and Bishop Thomas of Växjö consecrated the church on 22 January 1351.
Finnish National Board of Antiquities has named the church site as a national built heritage.
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.
