Tonsberg
Often Called Norway'S Oldest Town; The Medieval Castle Ruins On Slottsfjellet And The Oseberg Ship'S Home District · Tonsberg, Vestfold
Tonsberg, on the western shore of the Oslofjord in Vestfold, is often called Norway's oldest town. Tradition puts its founding before 900, and whatever the exact date, it was a royal seat and trading town in the Viking age and the Middle Ages. Above the centre rises Slottsfjellet, Castle Hill, where the ruins of the medieval fortress of Tunsberghus lie on the grass beside a lookout tower from the late 1800s. Below it, the Brygga waterfront fills with restaurants, boats and people on summer evenings. Tonsberg is also the home district of the Oseberg ship, the grandest Viking ship ever found, dug out of a burial mound at Slagen just north of town in 1904. The honest caveat: the ship itself is in Oslo, and the museum there is closed until 2027, so at the mound you see a grassy hill. Tonsberg is a pleasant, lived-in coastal town rather than a museum piece - best as a summer stop on the way to the islands of Tjome and Verdens Ende.
