The City as Collective Memory
Rossi's central proposition is that the city functions as a repository of collective memory, accumulating meaning through the persistence of urban artifacts -- buildings, streets, and public spaces -- that outlast the specific functions for which they were originally created. A Roman amphitheater becomes a medieval market square; a monastery becomes a museum. This permanence of form despite changing use challenges the modernist assumption that form should follow function and suggests instead that the most valuable urban artifacts are those flexible enough to serve purposes their creators never imagined.
