In this study, changes that have taken place in the historical centre of León (Spain) and Puebla (Mexico) are analysed and compared to show that the same problems occur in the old quarter of both cities. Factors determinig these problems, such as loss of vitality and physical and social deterioration, are highlighted in the two case studies. The implementation of a Sustainable Urban Integration and Rehabilitation Strategy, based on functional, formal, social and environmental characteristics, is proposed. The results are expressed as the preservation of historical heritage, and changes in land use and its environmental conditions.
