During the 1970s, Sergio Larraín García-Moreno became aware of the importance his collection has acquired and of the urgency of worrying about its full and permanent maintenance, with an institutional safeguard beyond contingencies. Then, it initiates conversations with university and state entities with the intention of making a donation so that the collection is exhibited, conserved and increased. After some attempts, he finds an enthusiastic response from the Mayor of Santiago, Patricio Mekis, who welcomes the idea and begins to work to find a property that will shelter the institution.
Simultaneously, Sergio Larraín instructs the lawyer Julio Philippi I. a legal model that would serve to give birth to a stable institution, which would guard the objects, ensure their integrity and give them a destination under the guidelines and founding principles. This is how the Larraín Echenique Family Foundation came into being, which was named as a way of demonstrating that it was his heirs, and not the collector himself, who donated the collections to create and maintain a museum oriented to their care, study and dissemination. In this way, through an agreement between the Foundation and the Illustrious Municipality of Santiago, who contributes the building and the general expenses of administration, in December of 1981 the Chilean Museum of Pre-Columbian Art opens its doors to the public.
The Museum of Pre-Columbian Art is located just 10 minutes from Almacruz Hotel and Convention Center.
