Annevoie Castle (Château d'Annevoie) is a château in the village of Annevoie-Rouillon located in Wallonia in the municipality of Anhée.
It was built in the 18th century by the Montpellier family, and is principally known for the extensive water gardens that surround it, the Jardins d'Annevoie, the only ones of their kind in Belgium. The design is basically French, but contains numerous English and Italian elements. The water is from the River Rouillon.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.
