An important point: buying online avoids the ticket office queue, but not the queue at the building’s entrance. The Atomium states that the booking time gives no priority at the entrance, and that there is no priority access, either at the entrance or at the elevator, except for people with reduced mobility (and one companion) and restaurant customers. Reseller sites promising a « skip-the-line » ticket cannot do any better.
How does the visit work?
- The ticket office (separate pavilion): ticket desk, restrooms, lockers (€1, refunded) and a mandatory stroller area. Without an e-ticket, you queue here first, then in a second line for the Atomium.
- The panorama (top sphere): an elevator ride up from the ground floor, a 360° view at 92 m (302 ft) high; in clear weather you can see as far as Antwerp, according to the Atomium. The elevator takes 18 people at most. Return by elevator to level 0.
- The exhibitions (4 spheres): escalators and stairs, with 80 steps up and 167 down. The permanent exhibition retraces Expo 58 and the history of the building; more than half of the visit is devoted to exhibitions, including digital arts.
- The viewpoint (side sphere): at 36 m (118 ft), a 150° view through the structure, recommended by the Atomium for photos.
According to Wikipedia, the central elevator was the fastest of its time (5 m/s / 16 ft/s) and one of the escalators in the inclined tubes is 35 m (115 ft) long. Of the nine spheres, each 18 m (59 ft) in diameter, six were open to the public in 1958; the current visit has five.
Rules that can get you refused entry
These points come from the official visitor regulations; they are rarely explained elsewhere.
- Food and drink: prohibited in the building, as are cans and glass bottles; a refused item thrown in the bin is considered lost.
- Strollers: prohibited in the building; an area is provided behind the ticket office.
- Suitcases and large bags: prohibited; leave them in the ticket office lockers.
- Animals: refused, except guide dogs.
- Child on your shoulders, bare feet, sitting on the stairs: prohibited by the regulations.
- Under-16s on their own: they must be accompanied by an adult.
- Going out and coming back later: not possible, any exit is final.
Accessibility and health
Because of the complexity of the building, only the panorama is wheelchair accessible, according to the regulations (article 21). The elevator can cause dizziness. Passing through two of the tubes can bother people with epilepsy, and some temporary exhibitions (sound and light) can trigger seizures: the Atomium recommends that people affected check the dates of these exhibitions.
When to visit the Atomium
The Atomium itself gives crowd advice: come at opening time (10 am), avoid the peak from 11 am to 3 pm, and know that the flow eases from 5 pm. It also reports heavier attendance during Belgian and European school holidays and on weekends. As for weather, the panorama is best in clear conditions. We crossed the Uccle normals with sunset time, calculated at the Atomium.
| Month (15th) | Max temp at Uccle | Rain | Sunset | Sunset vs hours |
|---|---|---|---|---|
| January | 6.1 °C (43 °F) | 76 mm (3.0 in) | 17:05 | before last entry (5:30 pm) |
| February | 7.1 °C (45 °F) | 65 mm (2.6 in) | 17:58 | after closing |
| March | 10.9 °C (52 °F) | 59 mm (2.3 in) | 18:46 | after closing |
| April | 15.0 °C (59 °F) | 47 mm (1.9 in) | 20:37 | after closing |
| May | 18.4 °C (65 °F) | 60 mm (2.4 in) | 21:25 | after closing |
| June | 21.2 °C (70 °F) | 71 mm (2.8 in) | 21:58 | after closing |
| July | 23.2 °C (74 °F) | 77 mm (3.0 in) | 21:50 | after closing |
| August | 23.0 °C (73 °F) | 87 mm (3.4 in) | 21:03 | after closing |
| September | 19.5 °C (67 °F) | 65 mm (2.6 in) | 19:57 | after closing |
| October | 14.9 °C (59 °F) | 68 mm (2.7 in) | 18:50 | after closing |
| November | 9.9 °C (50 °F) | 76 mm (3.0 in) | 16:55 | before last entry (5:30 pm) |
| December | 6.6 °C (44 °F) | 87 mm (3.4 in) | 16:36 | before last entry (5:30 pm) |
How to read it: from November to January, the sun sets before the 5:30 pm last entry: arriving around 4 pm, you can watch Brussels light up from the panorama. In spring and summer, night falls well after closing. April is the driest month at Uccle (47 mm / 1.9 in); August and December the wettest (87 mm / 3.4 in). The Atomium is lit up every evening: the spheres carry networks of light points that evoke electrons, according to Wikipedia.
