The work proceeds from the assumption that it is possible to describe these connections between environment, territory and landscape by applying the Vitruvian triad, composed of Firmitas (solidity), Utilitas (utility) and Venustas(beauty). The environment, the sum of the conditions that influence all life, represents the place's solidity, because it guarantees its survival. In turn, territory is connected to utility, and through its etymological meaning is linked to possession, to a domain; while landscape, as an "area perceived by people", expresses the search for beauty in a given place, the process of critically interpreting a vision.
