According the first written record Gumlösa Church was inaugurated by archbishop Absalon of Lund in 1191. It is the oldest church in the Nordic countries built of brick. The vaulting and the tower were built already to the original church, which has been very unusual. The top of the tower was added in the 14th century.
Due the documents there were even 96 relics in Gumlösa church in the Middle Ages. The font, made of sandstone, dates from the 1100s. The other interior was mainly destroyed by fire in 1904.
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.
