Résumé en anglais
As heritage category, cultural routes constitute a complex system of tangible and intangible components linked by a basic element consisting in a land, water or mixed route. The setting of a cultural route results the ensemble of natural or cultural landscapes along the route. In the framework of the Spanish Intercontinental Royal Route project, the aim of this paper is to introduce the colonial routes system corresponding to present Argentine territory and, especially, the last southern part of the land route on the Atlantic side of South America. During Spanish administration period, three major routes converged in the city and harbour of Buenos Aires, coming from Peru, Chile and Paraguay. South from Buenos Aires, the route continued some 130 Km, up to the boundaries of the effectively occupied territories, linking some villages and rural settlements. The development of the Metropolitan Area took to the complete change of the route setting. Systematic survey and register were undertaken according to the methodology and instruments adopted by the ICOMOS International Scientific Committee on Cultural Routes (CIIC). Some principles are proposed in order to contribute to understand the significance of a cultural route in the context of a changing urban and rural setting.
