On March 12, 1940, the decree 735 of the Ministry of Public Education was issued, which would give life to the current Regional Museum of the Araucanía as the Araucan Museum of Temuco dependent on the Directorate of Libraries, Archives and Museums.
Regional Museum of La Araucanía, is the museum in charge of "conserve, investigate, disseminate and value the different cultural patrimonies that coexist in the region in their different times and spaces
The collections of the museum have their origin in the 1930s, when local researchers from Temuco began to collect and acquire different objects, especially representative of the Mapuche culture.
From 1940, with the foundation of the museum by decree of the Ministry of Education, its base collection is formalized, and increases with time through donations, destinations and archaeological research. Currently, the museum holds some 2,800 heritage objects, which are organized in different collections, according to their typology: historical, archaeological, ethnographic, pictorial, etc.
The rest of the pieces are safeguarded and conserved in duly authorized warehouses and with packaging systems adapted to their patrimonial relevance. However, this does not mean that they are not made known to the public, since one of the objectives of the temporary and thematic exhibitions organized by the museum is to showcase its collection.
In the same way, researchers can access the study of collections for the generation of knowledge. For this the museum also has a research collection, composed mainly of archaeological remains, scientific and reference samples, which by their condition are not exhibible to the public.
