If you're traveling to Brussels, the capital and largest city of Belgium, the iconic Atomium is a must-visit landmark. Originally built for the 1958 World Expo, its futuristic design captured global attention and has since become a symbol of Brussels — even though it wasn't intended to last beyond the event. Standing 102 meters tall, the Atomium features nine interconnected spheres linked by 20 tubes, representing an iron crystal magnified 165 billion times. It was designed to symbolize scientific progress, the central theme of Expo 1958.

Since then, each World Expo has left behind iconic architecture and ideas reflecting its era. This year, the Expo moves to Osaka, Japan — and CGTN will be bringing you the latest from the event. Stay tuned!
