Details
RMO lets Medusa, Pegasus and Anzu step out of the usual hero-versus-monster frame. They become characters with motives and powers, while a stamp card turns archaeology into observation, riddles and making rather than a list of dates. Daily through 30 August, children search among mummy cases, temples and antiquities for an escaped mythical creature; admission is free through age eighteen.
- The activity runs daily until 30 August and is aimed at ages seven plus; a preschool map starts at four.
- The quest and museum entry are free for children; adult admission is €14 and Museumkaart is valid.
- Opening hours are 10:00–17:00 daily, with Thursday evening opening as well.
- Collect the activity card at the exhibition entrance; busy afternoons may take longer.
Treat this as a small summer story with a clear setting, not simply another pin on a map. Times, ticket types and practical arrangements can still change. Reopen the official page before booking or leaving, and allow some margin for transport, weather and food so the day stays enjoyable.
Hokimi field note: Let each child choose one creature as the story’s hero, then follow that trail instead of trying to see every case.
