Perhaps no other figure exerted a greater influence on the urban transformation of Barcelona during the first third of the twentieth century than Josep Puig I Cadafalch. If as an architect he exemplified the tension between Modernism and Noucentisme, as a historian and archeologist he exemplified the recuperation of Catalonia's historical and patrimonial memory. Nevertheless, it was his awareness of town planning issues that contributed to the great metropolitan transformation of Barcelona, from the opening of Via Laietana to the development of the Placa de Catalunya. This volume includes both a biography and a chronology of works and projects.
