The topic of the International Workshop was identified thanks to the possibility of taking advantage, in the short time available, of research, surveys and experiences in urban restoration, which had already been carried out during the activity of the Master Executive in Architectural Restoration and Heritage Cultures. The Workshop was therefore planned with the aim of experimenting with different design paths also based on the understanding of the urban genesis of the block and able to offer new interpretations of its complex urban stratification. The contribution and commitment of José Ignacio Linazasoro, who generously accepted our invitation together with Luca Arcangeli, could only respond in the most learned and brilliant way to expectations, as the following pages show.
