Discover walls in all their forms

In the museum area of Liège-Guillemins station, Europa Expo presents its exhibition "Extra Muros, Beyond the Walls" from 22 April.

Do walls have ears? Let yourself be carried away by the secrets of the Great Wall of China to the Berlin Wall, by way of other walls such as the sound barrier. These emblematic walls offer an original reading of the world. These historical, psychological or even botanical walls reveal many facets of our reality.

Learn all about walls through immersive, interactive and surprising decors!
