This volume explores the urban spaces of the city—namely squares, streets, courtyards, and stairways—as sites of exchange and mediation. Through an interdisciplinary lens combining urban morphology, architectural history, and social geography, the authors examine how these micro-spaces function in the public realm: as thresholds between private and communal life, as connectors within the city’s circulation systems, and as repositories of memory and social interaction. The text is richly illustrated and organised as a sequence of urbanscopic fragments that map out the morphology of urban space and trace threads of transformation in Mediterranean and Southern-European contexts. Its contribution lies in re-emphasising the value of what are often considered secondary elements of the urban fabric and framing them as significant actors in the dynamics of public space, movement, and social life.
