Tuna Church is a brick-built medieval church dating from the 1200s. The porch was added in the 1400s and arches in 1500s. The present tower was erected in 1877. The interior is decorated with frescoes (oldest date from the 1300s, choir murals were added in 1620). The remarkable wooden Madonna sculpture is probably a North German work from the 1400s.
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.
