Aldo Rossi, one of the most important figures of the last century who determined and characterized the theoretical debate of international architecture, both in the academic and professional fields, died prematurely on September 1997. Translated into many languages, Rossi's The Architecture of the City (1966) soon became a reference for world-leading schools of architecture, bringing into focus the urban dimension of architectural design, and the fundamental role of history. In different occasions over the years, such themes have stirred up the debate from different standpoints, opening further lines of inquiry for generations of scholars and academics all over the world. The volume, introduced by a theoretical essay, consists of four sections corresponding to four thematic issues: "Theory & Design"; "Teaching & Design"; "International Design Legacy"; "Design".
