From Iron Age ice-skates to Renaissance triptychs, Sweden’s prime historical collection spans nearly 14,000 years of Swedish history and culture. The undisputed highlight is the subterranean Gold Room, a brooding chamber gleaming with Viking bling and rare historical jewels. The most astonishing artefact is the 5th-century, seven-ringed gold collar with 458 carved figures, which weighs 823g. Found in Västergötland in the 19th century, it was probably used by pagan priests in ritualistic ceremonies. To use the museum’s fantastic free digital audio guides, bring some ID.
