Hi there,

I have to disagree with Victor,

The aquarium is not really worth a visit. It is very expensive and if you have seen good aquariums before you might be disappointed.

Also I would ad these to your list;

Casa Batllò
La Pedrera
Parc Güell
Cathedral Santa del Mar
Hospital Sant Pau

The lists above and from Victor are quite basic.
If anybody needs some more information about certain things, don't hesitate to ask me.
