The book is about the theory of urbanism. The scope of its study is in the interest of physical planning and urban design. In this book, theoretical inquiries are focused on the dismantlement and unveiling the meanings of the built environment and its urban world. The strength of the book lies in its nature as a philosophical and historical investigation, especially in asking the fundamental questions of urbanism according to its nature, function, and institution, rather than simply supplying wide- ranging perspectives of already available theories in publication. The approach and analysis of the study is hermeneutic phenomenological that concerns with the relationship between concepts and phenomena of urban settlement. The purpose is to expound the concepts, functions,and organizations of urbanism and its historical and cultural context. All this is in the hope that this study is able to support, enrich, and enhance urban studies as an interdisciplinary platform for design,humanities and social sciences.
