I visited Belgium, with my father, back when I was 15.Poor Belgium! If it's any consolation to you, if I ever invaded Belgium it would be for the chocolate.
Incidentally, Belgium happens to be one of only three European countries I've ever been to, though I was too young to have any memories.
Well, we only went to Brussels (it was a trip to Amsterdam-Brussels-Luxemburg). I remember the Atomium and that I bought some game for my Gameboy in one of the department stores. Don't recall if we went to the area with the characteristically shaped Eu building (with the three sides) or if I just remember that from school books.
