See the Atomium’s unusual design from the outside, then head up to its highest sphere, which stands at around 300 feet (92 meters), has a glass roof, and offers 360° views of Brussels. This level also houses the Atomium Restaurant, which serves brasserie-style dishes with the finest views in Belgium.
Visit the Atomium’s permanent exhibit to learn about the structure’s history, and explore the temporary exhibits hosted in the spheres—which range from an exploration of the Universal Declaration of Human Rights to three-dimensional versions of paintings by Bruegel. For priority access, pre-book a guided tour of the Atomium; you can also access the sight with a Brussels Card, which gives you unlimited access to a huge number of city attractions.
