Abstract : Increasingly, the Mediterranean countries, offers a complete tourist traditionally resort by formulas that respect the environment and local culture. This new approach of tourism, which some qualify sustainable, is based on the rich local patrimonial richnesses. The issue of patrimonial richnessesis then not only institutions but also individuals who are increasingly involved. No one will be surprised if, indigenous or expatriate, individuals begin a process of patrimonialization. Using the technologies of information and communication they offer a positive image and invite sharing their knowledge, their emotions through theirs personal visions of the patrimonial richnesses of their regions, their country. Through blogs and Web sites devoted to all forms of patrimonial richnesses in Tunisia, we propose to examine the ownership of the issue of patrimonial richnesses and analyze the types of communications.
