During the Middle Ages Cunerakerk was an important pilgrimage site. The church has stored the relics of the Saint Cunera since the 8th century. The first church on site was dedicated to Petrus (before 11th century). In the 11th century the church was dedicated to Saint Cunera. A legend tells about her stay at the court of king Radboud in Rhenen. The church was built and enlarged in the 15th century. The tower was built from 1492 until 1531 and its design is inspired by the Domtoren in Utrecht.
Since the Reformation in 1580 the Cunerachurch is in use by the Protestants. The relics of Cunera are spread since then.
The church has often been damaged. In 1897 the tower burned and a restoration was done with a different spire (designed by Pierre Cuypers). During the next restoration in 1934 the roof burned down and during restoration of the roof a section collapsed. In 1940 the tower and church were damaged by war, and in 1945 it was again heavily damaged by the war. The building material used for subsequent repairs was so bad that in 1968 restoration of the tower was necessary again.
The rood screen of the choir was built in 1550 in the Renaissance style. It is one of the few rood screens still existing in the Netherlands. It is decorated with allegoric images of the three theological virtues: faith, hope and love. Part of the sculpture is gone. The choir stalls were cut in 1570.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.
