Atomium

Me and my family go to Belgium every year to spent the christmas holydays with my grandparents. One years we went to Atomium, a scientist museum were is explained all about the atoms, DNA, molecules,... 

The musuem have a molecule structure, and the spheres thera are big rooms were there are experiments, videos and other things to explain the history of the museum and biology. The way you have to pass through a sphere to another is with bridges, were you can ascent or descent, and in these ladders and corridors are a lot of lights and musics. In total there are 9 spheres.

Is the symbol of Brussels and Belgium. It's a big building made of stainless aluminium that represents an iron crystal.
