Mont Orgueil is a castle in Jersey Island. The site had been fortified in the prehistoric period, but the construction of the castle was undertaken following the division of the Duchy of Normandy in 1204. The castle was first mentioned in 1212. The castle was the primary defence of the Island until the development of gunpowder which then rendered the castle ultimately indefensible from Mont Saint Nicholas, the adjacent hill which overlooks the castle.
Mont Orgueil was updated with platforms for artillery constructed in 1548 and 1549 under the direction of Henry Cornish, Lieutenant of the Earl of Hertford in Jersey. Mont Orgueil was to be superseded by Elizabeth Castle off Saint Helier, the construction of which commenced at the end of 16th century. Walter Raleigh, Governor of Jersey in 1600, rejected a plan to demolish the old castle in order to recycle the stone for the new fortifications.
The old castle continued to be used as the Island's only prison until the construction of a prison in St. Helier at the end of the 17th century. A report for the States of Jersey in 1691 declared that the barracks accommodation was so dilapidated that it was impossible to quarter troops there. Two years later, the castle was stated to be in a ruinous condition and subsequently was abandoned as a prison. This was because Elizabeth Castle had been built and the castle was neglected and not needed any more. Repairs were carried out 1730-1734 and for the rest of century parts of the castle were adapted for garrison accommodation.
In 1800 the Corbelled Tower was fitted out for use by Admiral Philippe d'Auvergne as his headquarters for the secret service organisation he was running in Brittany and mainland Normandy. Until the second half of the 19th century the castle was open to the public on one day a year, Easter Monday, and crowds used to flock from all over the Island. This is believed to be a survival of the pre-Reformation custom of visiting St. George's Chapel inside the castle on St. George's Day. In a generally ruinous state at the time of its handover to the people of Jersey by the Crown on 28 June 1907, Mont Orgueil has been managed as a museum site since 1929, although during the Second World War German Occupation (1940–1945) the occupying forces garrisoned the castle and added modern fortifications camouflaged to blend in with existing structures.
The heritage site has been managed by the Jersey Heritage Trust since 1994. In the early 21st century, the Trust planned to build a Tudor hall within the castle's keep. On 2 April 2006, after a long building programme the castle was reopened to the public by the Lieutenant-Governor of Jersey. Restoration work has opened up previously inaccessible areas of the castle to the public. Newly built additions in modern style have enclosed sections of the castle and made them weatherproof, parts of the structure have been reinterpreted, and artistic interventions in the grounds and structure of the castle have provided attractions for visitors.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.
