Abstract
San Francisco de Borjas Sanatorium of Fon-tilles was founded in 1905 for the treatment of leprosy. In its current configuration, the Sanatorium consists of a set of 29 buildings from different ages and styles. This large heritage has been promoted to join the International Coalition of Historic Sites of Exclusion and Resistance project, and aims to declare it as Heritage Site by UNESCO. The graphical analysis allows the definition of the set and the characterization of landscape, as a previous step to the formulation of a Landscape Program that articulates the set of measures and actions in order to preserve, improve and enhance the outstanding quality of the set.
