Adult evenings - To Heureka without children
Did you know that Heureka organizes events only aimed at adults? On this page you can find information about upcoming adult nights and learn more about the differences between our event concepts, H18 and NOX.
In addition to the special program for adults' evenings , Heureka's exhibitions are also open as usual. This allows you to explore the exhibitions in peace among adults. Heureka is a drinking area during adults' evenings - so you can explore the exhibitions with a glass of wine in hand! Further down on this page you will also find a list of all the exhibitions on display at Heureka.
