The volume reports the interventions carried out at the conference of the International School in Archeology (Certosa di Pontignano, 26 January-1 February 2001) on the relationship between the conservation of the evidence of the history of cities and current and future transformations of urban settlements. The 'archaeological-urbanistic' problem is therefore tackled by dealing on the one hand with the significance of the archaeological and monumental remains for the current inhabitants of historic cities; on the other hand by analyzing the age-old problem of the relationship between protection and transformation. Thus the first section of the text focuses on the first question; the second section traces the history of the theoretical question of safeguarding the historic centers of cities. Finally, the third section enters the current debate (theoretical and institutional) on the conservation of urban heritage, bringing the testimonies of very diversified international experiences.
