The history of the Sjundby manor castle dates back to year 1417. The present main building was built in the 1560’s by Jakob Henriksson. It was made of grey stone and had also a defensive purpose. Sjundby has been a residence for several noble families. The most well-known owner was Sigfrid Wasa, the daugher of the king Eric XIV. After her Adlercreutz family had owned Sjundby over 300 years to the present. Only exception was in 1944-1956, when the Porkkala area was rent to Russians and used as a garrison.
Sjundby is one of the finest stone buildings in Finland. The castle is in private possession but is also open to visitors (contact info@seaction.com).
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.
