The Atomium, an iconic structure of Brussels, stands as a testament to both architectural ingenuity and the spirit of the 1958 Brussels World Expo. Designed by engineer André Waterkeyn and architects André and Jean Polak, it symbolizes the atomic age and scientific progress. The nine spheres of the Atomium represent an iron crystal magnified 165 billion times, and it now serves as a museum, offering panoramic views of Brussels from its top sphere. After its renovation between 2004 and 2006, the Atomium continues to captivate visitors with its futuristic design and historical significance.
