Cartographic analysis provides a wealth of information when original sources are subjected to scrutiny with ITC tools. The cities studied here, on opposite shores of the Mediterranean, apparently different and supposedly incomparable morphologically, exhibit some akin structural traits. They interest us here, to evaluate the systems inherent to their performance. Both cities evolved from a small nucleus and have strong geographical links and exchanges with their peripheries, and grew from from an industrial and historical background to a varied economy, in which its touristic coastline certainly shows. The tools applied, derived from Syntax techniques, as originally developed by Hillier and Hanson (1984) and their UCL colleagues, enable a revision of spatial networks qualities.
