As a result of the development of the sciences of conservation of cultural heritage, the new concept of Cultural Routes shows the evolution of ideas with respect to the vision of cultural properties, as well as the growing importance of values related to their setting and territorial scale, and reveals the macrostructure of heritage on different levels. This concept introduces a model for a new ethics of conservation that considers these values as a common heritage that goes beyond national borders, and which requires joint efforts. By respecting the intrinsic value of each individual element, the Cultural Route recognizes and emphasizes the value of all of its elements as substantive parts of a whole. It also helps to illustrate the contemporary social conception of cultural heritage values as a resource for sustainable social and economic development.
