"Barcelona, abans que el temps ho esborri" is a chronicle of the high bourgeoisie who made the industrial revolution in Catalonia. An ironical walk along the Barcelona of the twentieth-century through the memories inherited by one of its descendants, Javier Baladia, that takes us to the golden years of a cosmopolitan and cultured elite, who left us a legacy that has made today's Barcelona an international reference. The private life of a family. A personal portrait of the twentieth century.
