The Atomium stands as an iconic symbol of Brussels, representing both the city’s futuristic vision and its commitment to science and progress. Constructed for the 1958 Brussels World’s Fair (Expo 58), this unique structure has since become one of Belgium’s most recognizable landmarks.

The Design and Structure

The Atomium is designed to represent an iron crystal magnified 165 billion times. It consists of nine interconnected spheres, each with a diameter of 18 meters, connected by tubes measuring 3 meters in diameter and 23 meters in length. The entire structure stands 102 meters tall, providing visitors with panoramic views of Brussels from the uppermost sphere.

Historical Context

Designed by engineer André Waterkeyn, with architects André and Jean Polak, the Atomium was initially intended to last only for the duration of the Expo 58. However, its popularity and iconic status ensured its preservation and eventual restoration in the early 2000s.

Visiting the Atomium

Today, the Atomium serves as a museum and a cultural space. Visitors can explore exhibitions on the history of the structure, science, and design. The top sphere offers a stunning 360-degree view of Brussels and its surroundings, while other spheres house permanent and temporary exhibitions.
