Oslo Royal Palace (Kongelige Slott)

Worth it if you're into architecture and royal history rather than expecting lavish interiors—the 4.4 rating from over 4,400 reviews suggests it delivers on those fronts consistently. The sheer number of guided tour options (63 on Viator alone) means you can pick your depth level, though paid entry plus a guide will add up, so go if you're genuinely curious rather than ticking a box.
