Barcelona montjuic fridge magnet?

Question

I purchased a fridge magnet from barcelona that shows a building with a water feature in front of it and it says 'Barcelona Montjuic'. What is this building? Any information and links would be welcomed :)

Answer 1

Probably the castle on top of Montjuic called Castell de Montjuic or simply Montjuic castle. It used to be a watchtower.

Answer 2

Not Castell Montjuic, but probably the Palau Nacional, with the Magic Fountain in front of it.  Below the fountain is the very huge Plaza de Espanya, and the even huger transportation transfer center.  

This look like it?  http://www.inmagine.com/pts0805/WE020840...
