Atomium

Halfway between sculpture and architecture, the Atomium was designed and built for the Brussels World's Fair (1958), for which it was the flagship building and emblem. Representing an iron unit cell (9 iron atoms) magnified 165 billion times, the monument with its unique silhouette has, over time, grown to become the symbol of Brussels and Belgium. On the inside the Atomium offers, not just the most beautiful view of Brussels, but also an entirely astounding and surreal ride through its interior spaces and volumes which alone makes a visit worth it. The Atomium ticket automatically includes the entrance to the Design Museum Brussels (150m away).
