Cultural Petition in the preservation project

The preservation of the cultural estate, when faced in a sectorial and limited way, does not have any valuable validation in both theoretical and applied context. The preservation of movables, real estates or intangibles has different positive aims when it allows men to live in strict relation with the their environment practicing actions related to their cultural values. The methods that allow to recognize a value depend from the social, economic and political context where men have developed. The need to research these values rises from the opportunity to have real and cultural references that allow men to make their choices and to make sense to their present and future life. In this way the relation between values and needs rises. It is related to another interesting subject that deals with the change of the living condition in the today’s society that modifies the relation between preservation and fruition of monuments and of the whole city. These concepts are the foundation of theories and of interventions that are practiced to protect and preserve the heritage of the world. More precisely, if we analyze the methods and the intervention criteria performed in different social, cultural, economic and political contexts we can note a common factor related to the relation between the historical value and the use value. This last relationship is not submitted to fix criteria but, on the contrary, is based on continuous new interpretations strictly related to the cultural environment. Starting from these remarks, the main aim of the contribution is the presentation of some proposals related to different approaches of research and project in the context of the heritage preservation, focusing the attention on some extra-continental realities (in particular Colombia end Japan)
