This 103-meter-high sculpture is the pride of Brussels. It was built in 1958, for the World’s Fair and it represents a steel-aluminum construction of 9 atoms. It’s connected by tubes through which you can go around the sculpture and walk into a room or museum dedicated to the well-intention use of atomic energy. You can have a meal at the highest ball of the sculpture or visit the nearby park and museum of various models of tourist attractions of Europe.
