Oslo Museum

Halvdan Svartes gate 58, 0266 Oslo

The city museum in the old Frogner manor in the middle of Frognerparken tells Oslo's story across 1,000 years. Children and young people up to and including age 25 get in free, adults pay, and the first Thursday of every month is free for everyone. Children meet models, old objects and changing exhibitions, and outside lie the whole park and playground. A calm cultural stop that's easy with small children.
