These are therefore the three fundamental components of every ecomuseum, which simultaneously constitute its substance, content and working method.
1) The territory ,because the ecomuseum is not a building or a place, but it is diffused to the whole space, representing and making more visible its characteristics such as the landscape, the history, the memory, the identity.
2) The population, because it is the true subject-object of the Ecomuseum, because only its participation legitimizes its existence, because it is the succession of communities and populations in space and time that has created the landscape and heritage of a territory.
3) The heritage, because all the assets of the material culture (buildings, artifacts, works …) and the immaterial (knowledge, tastes, stories, traditions, trades, habits, …) is what the Ecomuseum intends to enhance, constitutes the identity of the territory and its community.
“The relationship with the population does not allow for discussions: it is the participation of the population that legitimizes the Ecomuseum. Participation, collaboration, competition, association, complicity, connivance, trust …: the search for close relations with the population is important, but also important how many subtly different forms this participation can take.” (Gèrard Collin, Ecomuseum of the ont Lozère) – (content taken from the website www.ecomuseovaltaleggio.it)
