Belgium's Atomium Celebrates 20 Years of Futuristic Brilliance in 2026
Belgium is marking the 20th anniversary of the Atomium's major renovation with a year-long celebration. The iconic Brussels landmark, originally built for the 1958 World Expo, has since become a symbol of modern design and scientific curiosity. Over 20 special events, including digital art and audio installations, will take place throughout 2026 to honour the occasion.
The Atomium was designed by André Waterkeyn as a striking representation of an iron molecule, magnified 165 billion times. Its nine interconnected spheres—five of which are open to visitors—were first unveiled at the 1958 World's Fair. The structure's futuristic appearance quickly made it a Belgian landmark.
In 2006, the Atomium underwent a complete transformation, with its original aluminium exterior replaced by durable stainless steel. This renovation not only modernised its look but also boosted its appeal, sending annual visitor numbers soaring from 150,000 to nearly 800,000.
To celebrate the anniversary, three new digital art installations will debut. Supply Chain by Roman Tardy uses mirrors, LED panels, and sound to create an immersive experience. Nimbus, designed by Visual System, reimagines the Atomium's geometric forms through dynamic light and sound. At night, Rotonde by Dirty Monitor will bathe the structure in shifting illuminations paired with an original soundtrack.
The celebrations also include scientific discovery weekends and playful collaborations with Belgian icons like the Smurfs and Manneken Pis. As a special gesture, anyone born on 18 February 2006—the exact day the renovation was completed—will receive free entry to the Atomium for the entire year.
The anniversary programme highlights the Atomium's enduring significance as both an architectural marvel and a cultural hub. With visitor numbers now five times higher than before the 2006 renovation, the landmark continues to draw global attention. The events scheduled for 2026 ensure its legacy remains vibrant for years to come.
