• Free for under-18s every day, and Wednesdays are free for everyone, so a short drop-in costs nothing
• No strollers in the galleries: leave yours in the lower-floor cloakroom (lift from the front garden) or borrow one of the museum's few strollers
• Come after lunch, since school groups fill the museum most mornings

Copenhagen's city history museum fills a historic building behind City Hall with more than 400 finds, from the Ice Age to today. Kids can stand over the skeleton of a medieval warrior who survived sword and axe blows, spot a Viking Age bone comb and a wooden bicycle, and explore a large interactive model of the city. Film, voices and sound installations tell the stories.
