The Norwegian fortress Fredriskberg lay strategically placed on Nordnes’ highest point with a precipitous cliff face to the sea on the west side. Dutch Engineer Major General Henrik Ruse (1624–79) initiated the fortress construction, planned with three bastions and a half bastion on the land side and a wall on the side adjacent to the cliff. The fort was built between 1666 and 1667. It was built after and in many respects because of the Battle of Vågen. It is named after King Fredrik III of Norway. The Nordnes Park was built 1888-1898 partly on some of the old fortifications.
