Belgium’s primary planetarium, born from a 1935 exposition and reborn in the 1970s on the Heysel Plateau, where it surveys the cosmos alongside the Atomium and modern entertainment venues.
At a glance
The Brussels Planetarium presents astronomical shows and exhibitions under a hemispherical dome. Located on the Heysel Plateau in Laeken, it neighbours the Bruparck entertainment complex and the iconic Atomium. The institution is administered by the Belgian Federal Science Policy Office.
History
The planetarium traces its origins to the Brussels International Exposition of 1935, when it opened as the Alberteum Aedes Scientiae under the patronage of King Albert I. The original facility operated until 1966. In the 1970s, a new building rose in its place, designed to house a modern planetarium. In 1979, the institution was formally integrated into the Royal Observatory of Belgium, establishing its current governance structure within the federal science administration.
What you see
The 1970s-era building employs contemporary design principles suited to its scientific mission. The planetarium’s defining feature is its projection dome, which creates an immersive environment for astronomical displays and educational programmes.
Cultural significance
As Belgium’s principal planetarium, the institution serves both educational and public engagement roles. Its location within the Heysel Plateau cultural complex—alongside Mini-Europe and Kinepolis—positions it as a cornerstone of Brussels’s scientific and recreational infrastructure. The facility bridges mid-twentieth-century exposition culture with contemporary science communication.
