The Norman Château de Caen was built in c. 1060 by William the Conqueror, who successfully conquered England in 1066. His son Henry I then built the Saint Georges church, a keep (1123) and a large hall for the Duke Court. At Christmas 1182, a royal court celebration for Christmas in the aula of Caen Castle brought together Henry II and his sons, Richard the Lionheart and John Lackland, receiving more than a thousand knights. Caen Castle, along with all of Normandy, was handed over to the French Crown in 1204. Philip II reinforced the fortifications.The castle saw several engagements during the Hundred Years' War (1346, 1417, 1450).
The keep was pulled down in 1793 during the French Revolution, by order of the National Convention.The castle, which was used as a barracks during World War II, was bombed in 1944 and seriously damaged.In 1946, Michel de Boüard, an archeologist from Caen decided to start excavations in the area of the castle to bring to the light medieval traces. The musée des Beaux-Arts, which was installed in 1967, opened in 1971.
The castle was constructed on a hillock and is now in the middle of the city. With an area of 5.5 hectares, it is one of the largest castles in Western Europe. It remained an essential feature of Norman strategy and policy.
Today, the castle serves as a museum that houses the Museum of Fine Arts of Caen, Museum of Normandy along with many periodical exhibitions about arts and history, Saint Georges church and the Exchequer of Normandy, used as a temporary hall of exhibitions, which seated the Court of Normandy.
There is also a garden showing plants cultivated in the middle-ages. The keep, now razed, had a large square section with round towers at each corner. As the castle, it was also surrounded by a moat. The top of the ramparts offers a splendid view of Caen. Some parts of the curtain walls were built during the 12th century, most of them date from the 15th century.References:
Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
