Preconception of Belgium

Before I visited or even did any research on Belgium, I added it to my map of the gaps. This is what was in my head about the country, from pop culture or hearsay or dimly remembered school. (Of course, actually going there will change this a lot.)

I know this is somewhere in Europe.  Name vaguely rings a bell.  Is Inspector Poirot from here?  Is this where “Belgian waffles” were invented?  Suddenly I am not very good at this.
