During the 1970s, Sergio Larraín García-Moreno became aware of the importance that his collection has acquired and of the urgency of worrying about its complete and permanent maintenance, with institutional protection beyond contingencies. Then, it initiates conversations with university and state entities with the intention of making a donation so that the collection is exhibited, preserved and increased. After some attempts, he finds an enthusiastic response in the Mayor of Santiago, Patricio Mekis, who embraces the idea and begins to work to find a property that houses the institution.
At the same time, Sergio Larraín entrusts the lawyer Julio Philippi I. with 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 founding guidelines and principles. In this way, the Fundación Familia Larraín Echenique arose, baptized as a way of showing that it was their heirs, and not the collector himself, who donated the collections to create and maintain a museum aimed at 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 administration expenses, in December 1981 the Chilean Museum of Pre-Columbian Art opens its doors to the public.
The Pre-Columbian Art Museum is located just 10 minutes from Almacruz Hotel and Convention Center.
