What constitutes a city? How does human settlement in a specific site create a civilization? Civitas, the latest issue of the 'Harvard Architectural Review', presents a series of provocative responses to these questions. Architects, critics, educators, and planners investigate the conflict between contemporary constructs of human settlement and more traditional definitions of cities. Through a combination of projects and theoretical essays, Civitas aims to provide a more diverse understanding of the nature of urbanism and community.
