On behalf of the Spanish architects FAM we were designing a structure for the monument dedicated to the victims of the terror attacks in Madrid of 11th March 2004. The outer layer of the 11-meter-tall monument at Atocha station is constructed of approx. 15,600 massive glass blocks. The glass blocks are connected with adhesive joints into a freely developed form. The internal layer is made of vacuum stabilized ETFE foil with printed sentences on it.
