The Heart of the City concept, which was introduced at CIAM 8 in 1951, has played an important role in architectural and urban debates. The Heart became the most important of the organic references used in the 1950s for defi ning a theory of urban form. This book focuses on both the historical and theoretical reinterpretation of this seminal concept. Divided into two main sections, both looking at differing ways in which the Heart has infl uenced more recent urban thinking, it illustrates the continuity and the complexities of the Heart of the City. In doing so, this book offers a new perspective on the signifi cance of public space and shows how The Heart of the City still resonates closely with contemporary debates about centrality, identity and the design of public space. It would be of interest to architects, academics and students of urban design and planning. Leonardo Zuccaro Marchi is an Italian architect, encompassing and tackling the ambiguous complexity and different ambassadorial roles and practices of architecture, both relying on fundamental historical-theoretical references and inspiring the advancement of innovative approaches. He graduated from A.S.P. Alta Scuola Politecnica, Politecnico di Milano and Politecnico di Torino. He received his PhD at IUAV and TU Delft Universities. He has been Post-doctoral Fellow at KTH University. He is currently Visiting Lecturer at TU Delft, Netherlands.
