We are proposing a graphic reconstruction of the condition of the significant fragments of Rosario Architecture and its history as a comparative sequence throughout the time in relation to the transformation of the site. We are looking forward to producing systematic documentation with multiple application using the CAD to generate an atlas: a platform that provides information. The redrawing of the buildings conditions proposes that the digital patrimony is transformed into a place of memory of the city architecture. Each building is entailed to possible presentations that this platform gives, generating a system always going on and never ending.
