Dendrochronological dating of wood samples indicate that Nore stave church was built after 1167. The church was built with galleries, a chancel and cross naves - an architectural style that was unique in Europe during the Middle Ages. This style is called the Nummedals-type. The church also has a central mast, that was originally the support for a tower, mostly likely containing church bells. The walls and ceiling of the interior are decorated with murals, among them scenes from the Bible presented as riddles. The chancel was replaced in 1683 and the spokes of the nave in the first half of 18th century.
In 1888, art historian, professor of art history and author, Lorentz Dietrichson (1834 - 1917), became the owner of the church. Professor Dietrichson, who had played a major role in founding the Society for the Preservation of Ancient Norwegian Monuments (Fortidsminneforeningen), donated the property to the society in 1890.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.
