No matter how you look at it...The Atomium was erected for th 1958 World's Fair in Brussels Belgium and since it was quite a hit, the nation decided to leave it up.
It is actually a unit cell of an iron crystal magnified 165,000,000,000 times and visitors can explore it from the inside as well as admire it from the outside.
