Geography and Design. The Via Francigena between Veio and the Vatican

«It is the great routes that emphasize the territory and reveal to us the meaning that humans attributed to the land and to the human–land relationship. These routes are still there because, even after the corresponding archaic techniques were surpassed, the more recent techniques could only build upon the previous ones» (Muratori, 1967). This quotation from Saverio Muratori’s Civiltà e Territorio provides the theoretical foundation for the analysis of the metropolitan stretch between Veio and San Pietro. The path is not simply a physical trace but a persistent manifestation of the historical relationship between humans and the land. The Francigena, in fact, is not an infrastructure created ex novo, but a continuous guiding thread that has been carefully grafted onto preexisting matrices. Its final trajectory follows and exploits the sedimentation of millennial paths, such as the Via Veientana, which served as the foundational trace for the first stretch of the consular Via Cassia. Despite the transformation of “techniques”–the replacement of pilgrims’ footsteps with asphalt and the speed of modern vehicles–the elongated form of the Parco di Veio and its thresholds remain defined by the same historic arteries (Cassia and Flaminia). The current road network is a functional superstructure grounded in the geological history and orography of the tuff landscape shaped by the Etruscans. In summary, the modern pilgrim’s route is the inevitable heir of the ancient track. The persistence of this “backbone” of the territory, even in its contemporary desacralization and metropolitan fragmentation, confirms that great routes are never truly surpassed but continue to dictate the morphology and stratigraphy of the places. This study offers a reading of this territory and proposes a design strategy to enhance the path–today difficult to traverse and enjoy–between Veio and Rome.
