Tervik manor was established in 1636 and the present empire style main building was built in 1736. Marshal de Geer made significant renovation to Tervik in 1810’s. It was remodeled in the Empire style during the reconstructions in the 1820s, and the appearance has been changed in 1924-1926 according to the design influenced by the architectural style of Classicism.
The longest alley of oak trees in Finland leads to the beautiful manor. There’s also one of the largest private collections of portraits. Tervik manor is privately owned, but open for groups (preorder required).
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.
