Slottsfjell Festival in Tonsberg
Slottsfjell is a music festival held on Slottsfjellet, a hill overlooking Tonsberg topped by medieval castle ruins, presenting a mixed program of Norwegian and international pop, rock and electronic artists. Available research surfaced a live festival website but could not confirm precise current-year dates or a fully verified artist lineup for 2026 specifically.
Tonsberg is frequently described as Norways oldest town, with roots tradition traces to the ninth century, and the hill that rises above it, Slottsfjellet, carries that history physically in the form of medieval castle ruins that once anchored a royal fortress overlooking the surrounding fjord landscape.
