I went to Spain this summer and went to a few malls but I can only remember the name of two.

Dos Mares-San Javier (Murcia)-I know this is a new mall because my friend who lives there told me all about it and we went to it several times while I was there. It doesn't have a ton of stores but it has a decent amount along with a movie theater.

El Corte Ingles-Murcia-This is not what I consider a mall but I was told it was a mall. It has floor after floor of clothes, book stores, etc. Along with my fav. store "Pull and Bear"
