The sculpture name is "El Alma del Ebro" by Jaume Plensa, I think this sculpture is awesome because it have all alphabet. I love it because whit this letters you can express your ideas, sentiment or communicate whit other lenguage. I think too, the artis want say other idea in the sculpture, this idea is that at this moment in the word the lenguage is destroy for cause of chat or people are create new lenguaje colloquial because of it i believe the sculpture had this hole in the head.
