The centre consists of two parts, the first of which is called 'Time Machine – The Human & The Bullet'. Set inside the brick tunnels of this 19th-century fortress, the exhibition recreates what the fort would have looked like when it was first built: complete with cannons, weaponry and lifelike mannequins in period uniform in active poses throughout the fort's atmospheric corridors.
The second part of the centre is the science part with 6 different interactive/multimedia exhibits. 'Around The World' takes you on a journey to explore and understand the environment and culture of each continent. Other exhibits like 'With Energy' and 'Puzzle' introduce children to physics and mathematical problems in a fun manner. Featuring plenty of machines, computers and interactive gadgets, Hevelianum encourages visitors to get hands-on and explains the complexities of science in an idiot-proof way. Opening hours for each part tend to change regularly so check their website!
The center's initiative 'Hevelianum without barriers’ allows all individuals, including those with a disability, to discover Gradowa Hill in many ways (NOTE: This excludes the 'Time Machine' section). There is also section "Playing with History", FREE of admission, with games including cannon training, a memory game and the possibility to try on old uniforms. They also have workshops and tours with educators, which is possible in English if you book in advance!
