Executive Summary: This report on the Roman community of Centocelle was produced as part of the studio class CRP 416: The European City, taught under the auspice of Prof. Bill Goldsmith, at the Cornell-in-Rome Program during the spring of 2004. In conjunction with this study, similar sociological investigations were carried out in three other Roman neighborhoods: Esquilino, Garbatella and Parioli. A preliminary note on the format of this report will be useful to the reader before proceeding further. Instead of a traditional academic format organized by subject or topic, this study takes on the form of what might be called an "episodic travelogue." The reader is taken on a guided narrative through the neighborhood according to a route an actual physical visitor to Centocelle might follow, and introduced to the sights and experiences that actual visitor might encounter. At several major points during the tour, roughly corresponding to the main sections of the report, further relevant information is elaborated to provide the reader with greater detail and an more intimate knowledge of the various aspects and important issues of the community. The map on the following page illustrates the route roughly followed by the report as it documents a narrative journey of discovery through Centocelle.
