The Church of Great Saint John the Baptist was built as a Gothic style fort-church probably in the end of 13th century but before 1330's. It is a typical Central-Estonian church with three naves. There is a rectangular east choir and tetragonal west tower. The portals of the church are remarkable. During the wars the pillars and arches of the church were destroyed. Supposedly, the church had round pillars. The wooden ceilings were built when the church was reconstructed.
Late baroque organ prospect (by Johann Andreas Stein, 1804) covers the organ made by the Kriisa brothers in 1937. The altar wall dates back to 1870 and was created by Johann Gottfried Mühlenhausen. The altar painting of church is “Jesus Christ on the Cross”. There is a monument of Hans Heinrich von Fersen, a memorial plaque for Alexander von Fersen, and a unique cross from 1598, one of the oldest in Estonia, in that church.
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.
