The last rays of sunset paint Brussels’ sky in deep purples and oranges as I emerge from the Heysel metro station. Ahead of me, the Atomium stands sentinel against the darkening sky, its massive spheres beginning to shimmer with the first hints of their nighttime illumination.
This 102-meter-tall architectural wonder, conceived for the 1958 World’s Fair as a representation of an iron crystal magnified 165 billion times, transforms as darkness falls into something altogether more magical.
A Different Kind of Twilight
The evening air carries a slight chill as I approach along the tree-lined path from the metro. Already, the structure’s enormous scale becomes apparent – each of its nine spheres measures 18 meters in diameter, connected by tubes that seem to defy gravity.
But it’s the play of light that captivates me most. As dusk deepens, thousands of LED lights begin their subtle dance across the stainless steel surface, creating an effect that makes the whole structure appear to hover in the growing darkness.
“The night brings out its true character,” whispers Marie, my guide for the evening’s photography tour. “During the day, it’s impressive. But at night?” She pauses, gesturing toward the illuminated spheres. “At night, it becomes something from another world.”
Timing is Everything
We time our ascent to coincide with the blue hour – that magical period just after sunset when the sky holds onto the last whispers of day. The journey upward is an experience in itself.
The escalators, housed within tubes angled at 35 degrees, create the extraordinary sensation of climbing through space. Through the windows, Brussels spreads out below, its lights beginning to twinkle in the gathering dusk.
Dinner Among the Stars
The top sphere houses the panoramic restaurant, where floor-to-ceiling windows offer a 360-degree view of the city. Chef Erik Van der Staede’s menu pays homage to Belgian cuisine while adding contemporary flair.
My North Sea sole arrives garnished with tiny grey shrimp – a classic Brussels combination – but it’s the setting that makes the meal extraordinary. As night fully descends, the city below becomes a carpet of lights, while the sphere’s gentle illumination creates an intimate atmosphere despite the vast space.
The prix fixe menu (€75 for three courses) changes seasonally, but the Belgian beef tenderloin with Chimay sauce has earned its place as a permanent fixture. Looking around at other diners, I notice everyone seems to pause between bites to gaze out at the breathtaking view.
Reservations are essential, especially for the coveted window tables, but even the central seating offers spectacular vistas.
Nocturnal Photography
After dinner, I join a small group of photographers positioning their tripods at what Marie calls “the sweet spot” – a location near the reflection pool where the Atomium’s full glory mirrors in the still water.
The structure’s nighttime illumination program runs in subtle cycles, shifting from cool whites to warm golds, each change reflected perfectly in the pool’s surface.
“Wait for the blue hour,” Marie advises, helping a newcomer adjust their camera settings.
“The contrast between the artificial lights and the natural sky creates magic.” She’s right – during this brief window, the photographs capture something almost otherworldly, the structure appearing to float between earth and sky.
Inside the Spheres After Dark
The evening exhibitions transform the interior spaces into something equally mesmerizing. In the permanent “Atoms in Space” exhibition, interactive displays take on new life in the dimmed lighting. Every half hour after sunset, a specially choreographed light show ripples through the structure, visible both from inside and out.
The “Brussels by Night” temporary exhibition offers a different perspective on the city’s evening character, with photographs and installations that capture the capital’s nocturnal soul. But it’s the unexpected moments that leave the deepest impression – watching the moon rise between the spheres, or catching the last rays of sunset reflecting off the steel surfaces.
A Living Monument
As the evening deepens, I discover the Atomium’s secret life after dark. The ground-level Food Truck Square has evolved into a local favorite, where Brussels residents gather for evening meals. The scent of traditional Belgian frites mingles with more exotic offerings, while local musicians often provide impromptu entertainment on summer evenings.
Small groups of photographers come and go, each seeking their own perfect shot. Some arrive equipped with professional gear and tripods, others simply with smartphones, but all share the same sense of wonder as they gaze upward at this impossible structure against the night sky.
Practical Twilight Magic
The last metro back to the city center leaves at 12:30 AM, but night buses (the N18) continue until 3 AM on weekends. Smart visitors arrive about an hour before sunset to watch the transformation from day to night, perhaps joining one of the monthly full moon tours (€25) or special photography workshops (€45).
As I prepare to leave, I pause for one final look. A thin mist has begun to gather around the base of the structure, making it appear even more otherworldly. The spheres glow like captured stars, their light reflecting off the low clouds. Standing here in the quiet of night, it’s easy to understand why this remarkable structure continues to capture imaginations more than 60 years after its creation.
