The construction and actualization of the notion of nation needs mechanism to assist in the selection of which elements (materials and symbolic) and subjects are going to be included in it. In this context, we are interested in inquiring Heritage process as one of such mechanism. We propose, through the study of Heritage construction, to identified and analyze: (i) the main actors involved; (ii) the elements, subjects and places chosen, and (iii) the symbolic spatial implications. We discuss these issues by examining the National Commission of Museums, Monuments and Historic Assets (CNMMLH) of Argentina, institution in charge of national heritage recognition, between 1984-1993, term, moment in which democracy is reestablish in the country. We conclude that national heritage activates versions about the past, identities and territories which contribute to consolidate a type of "imagined community" and its geographical symbolic limits.
