Atomium, Brussels (must see)

A fascinating model of a molecule magnified 165 billion times, the Atomium structure was originally constructed for the 1958 World Fair in Brussels and has since become an iconic symbol of the city. Its enduring popularity is evident from the long queues on weekends and holidays for the lift to its observation deck and panoramic restaurant.

A visit here is divided into two parts: first, the lift swiftly transports you to the top sphere for fantastic views of the city, followed by an exploration of the other three spheres, accessible via a combination of escalators and stairs. The whole experience exudes retro charm, as the Atomium was a technological marvel of its time, boasting the world's fastest elevator and the world's longest escalator connecting the spheres. You can find reminders of its construction in scattered photographs throughout the structure, and the classy gift shop offers cool 1960s-era items for sale. Meanwhile, the spheres primarily serve as temporary exhibition spaces and house a café.

The Atomium is undeniably impressive when viewed from the ground, and the vistas from the top are as spectacular as you would imagine, with computer screens to help you identify landmarks. However, the truly civilized way to enjoy it is by reserving a prime spot in the top-floor restaurant, which is surprisingly affordable and offers a truly unique dining experience.

Why You Should Visit:
One of the few places where you can enjoy a panoramic view of the entire city, the Atomium offers a distinctive perspective.

Tip:
If you find the ticket line to be long, it's advisable to purchase tickets online. They can be scanned directly from your phone, saving you the hassle of waiting in an additional line.
