The Story Behind Belgium’s Giant Iron Crystal and Its Nine Silver Spheres
Nestled in the heart of Europe, where medieval cobblestone streets wind into bustling cityscapes, stands one of the most iconic and unusual monuments in the world , the Atomium. Located in Brussels, Belgium, this architectural marvel draws curiosity and admiration from millions of visitors every year. With its nine gleaming spheres suspended in space, the Atomium seems like a structure out of a futuristic dream. But why does it have nine balls? Is it worth stepping inside? What does this bizarre structure represent? And how has its purpose evolved over time?
Let’s take a deep dive into the story behind the Atomium , not just as a building, but as a symbol of human aspiration, scientific pride, and post-war optimism.
A Symbol Born of Hope and Science
To truly understand the Atomium, we must travel back to the mid-20th century , a time of recovery, innovation, and global ambition. World War II had left Europe in ruins, but a renewed sense of purpose was emerging. Science and technology were being celebrated as the keys to a brighter, more peaceful future. The future wasn’t just about rebuilding , it was about dreaming big.
In 1958, Brussels was chosen to host the World’s Fair, officially known as Expo 58 , the first major World Expo after World War II. The theme was “A World View – A New Humanism,” and it was meant to showcase humanity’s progress in the wake of devastation, emphasizing scientific breakthroughs and international cooperation.
Belgian engineer André Waterkeyn was tasked with designing a structure that would embody this theme. Rather than designing a typical pavilion or tower, he looked to the invisible foundations of the physical world , atoms. Waterkeyn envisioned a tribute to the atom as a building block of both life and modern science. Thus, the Atomium was born.
Why Does the Atomium Have Nine Balls?
The Atomium’s nine silver spheres are not random design choices. They form the shape of an iron crystal magnified 165 billion times.
But why iron? Iron was a fundamental element of the industrial age , a material that built cities, powered locomotives, and created tools that shaped civilization. In this way, iron stood for strength, progress, and human ingenuity. Waterkeyn chose the iron atom as the model to represent not only Belgium’s industrial power but also the scientific optimism of the era.
The nine spheres represent the nine atoms in an iron unit cell, arranged in a body-centered cubic structure. Each sphere is 18 meters (nearly 60 feet) in diameter and is connected by tubes that are 3 meters wide and up to 35 meters long, containing stairs, escalators, and elevators.
In its design, the Atomium beautifully marries art, science, and architecture. It’s a giant molecular sculpture come to life , and unlike any other building on Earth.
Is It Worth Going Inside the Atomium?
Absolutely , and here’s why.
From the outside, the Atomium is visually arresting, a chrome-colored constellation rising above the landscape. But going inside transforms the experience from aesthetic appreciation to an immersive journey through time, space, and science.
1. Panoramic Views of Brussels
One of the top highlights of entering the Atomium is taking the elevator to the top sphere, which offers spectacular 360-degree views of Brussels and beyond. On clear days, you can see as far as Antwerp. The elevator itself was a marvel in its time, being one of the fastest in the world when installed in 1958.
2. Museum and Exhibitions
Several of the spheres are open to the public and house interactive exhibitions on science, design, and the history of the Atomium itself. You’ll learn about Expo 58, the cultural context in which the structure was created, and how its message has evolved with time.
Some exhibitions are permanent, while others are rotating, covering topics like space exploration, sustainability, or Belgian culture. These exhibitions make the Atomium a living museum, not just a relic of the past.
3. The Light Tunnel and Escalators
Connecting the spheres are long, dimly lit escalators punctuated by glowing LED installations. Walking through these tunnels feels like traversing a sci-fi spaceship. The combination of light, steel, and sound creates a futuristic vibe that appeals to both children and adults.
4. The Kids’ Sphere
One of the spheres is specially designated for educational programs and overnight school visits. Known as the “Kids’ Sphere,” it allows children to sleep inside the Atomium , a unique and unforgettable experience.
5. The Restaurant in the Sky
The top sphere also houses a restaurant with a panoramic view. Dining inside a steel atom while looking over the rooftops of Brussels is a once-in-a-lifetime experience. Whether you’re sipping Belgian beer or tasting local cuisine, the ambiance adds an unforgettable layer to your meal.
What Does the Atomium Symbolize?
At its core, the Atomium symbolizes progress through science and human unity. In 1958, the atomic age was seen not only as a technological frontier but also a hopeful horizon. While nuclear weapons had cast a long shadow over humanity, atomic science also promised cleaner energy, medical breakthroughs, and a new understanding of the universe.
Waterkeyn’s design chose to emphasize the positive potential of atomic science , a utopian vision where knowledge could unify humanity, rather than divide it.
In a broader sense, the Atomium stands for the spirit of Expo 58 , a world driven by optimism, creativity, and a desire for peace. It celebrates internationalism, the courage to dream, and the drive to build a better future.
Over the decades, as societal attitudes towards technology, globalization, and sustainability have evolved, the Atomium’s symbolism has remained flexible. Today, it is seen not only as a retro-futuristic icon but also as a cultural bridge between the past and future.
What Is the Atomium Used for Today?
After Expo 58 ended, most of the fair’s pavilions were dismantled. The Atomium was originally supposed to be taken down as well , it wasn’t meant to be a permanent structure. But public affection for it was so strong that the Belgian government decided to preserve it.
Today, the Atomium functions as:
1. A Museum and Exhibition Space
The primary use of the Atomium today is as a museum. It houses both permanent and temporary exhibitions related to art, science, history, and culture.
2. A Symbol of National Pride
Just as the Eiffel Tower symbolizes France, the Atomium has become a national symbol of Belgium. It’s featured on stamps, coins, and postcards and is one of the country’s most recognizable landmarks.
3. A Cultural Venue
The Atomium often collaborates with artists, filmmakers, and educational institutions to host events, concerts, light shows, and creative installations.
4. A Tourist Attraction
With over 600,000 visitors a year, the Atomium is one of Brussels’ top tourist destinations. Visitors come not just to marvel at its design, but also to engage with its exhibits and enjoy the panoramic views.
