If your busy schedule allows you to visit only one mellow old town along the Oslofjord, make it this one. Lying at the mouth of Glomma River, Fredrikstad is Norway's oldest fortified town. Visitors come here mainly to see the Old Town (Gamlebyen), one of the best preserved in eastern Norway.
King Fredrik II founded the town as a trading post between the mainland of Europe and western Scandinavia. Its characteristic landmarks are the 1880 cathedral and its delicate, silver-arched Glomma Bridge, which stretches 824m (2,703 ft.) from end to end and rises 40m (131 ft.) over the water.
