Yes indeed, Brussels is a strange city. Their most recognized symbol is a little boy with a blatter that always seems to be full. There is even a statue of a dog relieving himself in the city. You can also find murals of comic book characters all over the place. So really, it shouldn't sound strange that another iconic symbol is a bunch of 59' balls stuck together, which are actually part of the structure that represents an iron crystal magnified 160,000,000,000 times.
Where else but Brussels?
