• Built to be touched, since every exhibit is meant to be handled, and kids visit with an adult
• Free entry on Thursdays at the Błękitny Baranek granary, the cheapest day to go
• History panels in English, so kids who read no Polish can follow the story of the port

Historia Wyspy Spichrzów (History of Granary Island) is a hands-on permanent exhibit by the Archaeological Museum on the second floor of the Błękitny Baranek granary. Kids race barrels down a timed track, haul on a pulley block, open barrels that play the sounds of a medieval port and study a granary model. A cinema shows an 11-minute cartoon about Johanek, a poor fiddler who takes work as a porter.
