Designed to symbolize peace amongst nations, a belief in scientific research while having a positive vision for the future, this 102 metres tall marvel was built during the 1958 World Expo of Brussels. The nine stainless steel spheres enclose staircases, escalators and lift in the central tube that connects to the five habitable spheres, which homes public spaces and exhibit halls. With a mighty restaurant at the top, this iconic building sets an inspiration to Belgium and the World.
