• Book ahead on rainy days, when visitor numbers jump and tickets sell out, so buy online before you go
• Tickets at the Shelter Barracks, next to the fort's main square (the majdan), where the info point sits on level -1
• A climb from the station, since the fort is uphill: take the stairs by the bus station, or drive to the top car park by the majdan

Hevelianum fills the barracks and casemates of a 19th-century fort on Góra Gradowa, the hill above the Main Town. Around the World crosses seven continents, With Energy! is hands-on energy experiments, and Puzzle is logic and math challenges. In Playing with History, kids try on old uniforms and fire a virtual cannon by gesture. Outside, 20 hectares of paths lead to a playground and lookouts over the old city.
