Barcelona has generated a comprehensive compendium of its urban experiences that has been described by many authors, from Manuel de Solà-Morales to Joan Busquets, through Josep M. Huertas Claveria, Lluís Permanyer or Alexandre Cirici and Itziar González, among others. Their contributions present the history, urban events or relationships between public institutions and citizens. This book, however, presents the essence of a teaching and research project course format, organized by way of visits and city tours as part of the teaching program at UPC-s Escola Tècnica Superior D-Arquitectura de Barcelona, which uses the city as a classroom and laboratory.
