This is the story of Ribas & Ribas, a Barcelona based studio dedicated more than fifty years to architecture, through which we can follow its evolution and interpret the changes in this art in a period of great transformations, both at home and abroad. This commemorative book compiles, under the direction of Daniel Giralt-Miracle, the most outstanding and representative projects of the studio. A rigorous and fully illustrated chronicle of half a century of architecture, in a beautifully produced edition.
