On October 5, 1995, a group of young architects and artists began a four-day tour on foot through Rome’s expansive outskirts. The event concluded when the tour’s participants, all school companions who lived and worked in the capital, succeeded in reaching their initial point of departure. While conducted well outside the city’s densely settled urban fabric, the Walk about Rome never strayed beyond the official city limits. The explorers nonetheless traversed entirely unfamiliar and uncharted territories, entering in the process some of the most unusual environments to be found anywhere in Europe. Nestled within these natural folds within the city proper were hidden worlds inhabited by undocumented immigrants as well as pastures for grazing sheep; many areas were neglected and in a state of abandon.
