Fredriksten Fortress is Norway's largest and most important border fortress. It towers impressively over slag heaps and is visible from far away. The fortress was besieged several times but never taken and played an important role in Norway's independence. The complex is well worth seeing and offers various tours (e.g. ghost tour) at the information desk/café. All information boards are in Norwegian and English. Some paths are more difficult to walk, sturdy shoes are recommended.
