Although the proposal is based upon updating the built heritage inventory, in reality this project invites us to develop the first ever inventory of the region, as a recently established territorial and administrative unit. Our proposal seeks to provide a participatory methodology by opening up to citizen voices, as well as key actors within the fields of culture, heritage and landscape, fundamental to highlight the elements of heritage that until now have only been valued locally.

​

In turn, the absence of a pre-existing inventory that addresses the territory as a region (since the previous inventory only addresses it as a province of the Biobío Region and had 51 elements), and the possibility of multiplying the number of properties and areas of value by a factor of 6 (that is, to be able to reach more than 300), provides the necessary conditions to implement a methodology of identification aimed at highlighting the close link between the built cultural heritage sites and the landscape that surrounds it, as interrelated entities, in permanent dialogue.

​

The study will carry out an exhaustive historical and contextual analysis, crucial in order to contextualise each property and area of ​​value, but also to configure the narrative that will structure the chronological development of the history and identities of the region. In this understanding, our ethical and epistemic criteria will address the territory in the recognition of its cultural diversity, considering an approach towards gender and promoting a multidimensional narrative from the methodological theoretical tools of urban cultural studies, social history and the historical framework of the architecture theory.
