Often compared to an intergalactic spaceship worthy of the science-fiction film 2001 a Space Odyssey or a submarine décor; inside, the Atomium provides a surreal walk through astounding spaces and volumes and which are alone, worth a visit, such as the stainless steel cupolas [18m in diameter] supported by an impressive metal frame, or the tubes that house escalators and animations [sound & light].

This unique interior in the world is the result of the collaboration between the brothers André and Jean Polak and the engineer André Waterkeyn.

In addition, the Atomium is regularly used as a stage for large-scale multi-level digital installations. These installations are specially designed for the building and immerse the visitor in a dreamlike world that uses all the senses.
