Nidaros Cathedral

Nidaros Cathedral is the world’s northernmost medieval cathedral and Norway’s national sanctuary. The Cathedral is the grave church of St. Olav, the patron Saint of Norway. In addition to it now being one of Europe’s major historical pilgrim destinations, coronations and royal blessings take place in the church.

Trondheim was traditionally protected with fortifications by the river Nidelven and Skansen, but the city was vulnerable to attack from the east. The Fortress was therefore put on a hill to protect the city centre and control the area from Ila to Lade. 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. Two new isolated defensive works were also built to the east – Grüner’s and Frølich’s redoubts – but they are hardly visible today.
