extended to the constructions of buildings for workshops, offices and a new square. Additionally, the maintenance warehouses of the museum were remodeled, as well as the cafeteria, the library and the store. The design of the new spaces was the work of the Mexican architect Mauricio Rocha Iturbide, who was meant to interpret Diego's initial project, achieving a dialogue between the original Anahuacalli building and the new structures. In other words, an interchange between contemporary art and pre-Hispanic art and architecture. Since the Anahuacalli style corresponds to the principles of organic architecture, it was sought that the new spaces harmonize with the natural landscape. In this regard, structural supports were used in order to raise the base of the buildings in such a way that they respect the rocky surface. The project involved the participation of the engineer Santiago Sánchez Aedo and his building company Arquitech, for the construction of the structures. Among the new spaces, the Collections Warehouse highlights, destined for the protection, conservation, restoration, study and even exhibition to researchers, of the pieces of the pre-Columbian collection bequeathed by Diego Rivera. The treasures that are not permanently exhibited in the main building are kept in this room, nevertheless, those pieces enjoy the same artistic, historical and cultural importance than the ones that are on public display. The new Anahuacalli spaces, inaugurated in September 2021, are the following: Sapo-Rana Library: part of the Rivera's original project inaugurated in 1964, a traditional and multidisciplinary space that has been beautifully remodelled. Plazuela Ruth: exterior space in dialogue with nature; outdoors and ideal for cultural and social activities of various kinds. Dance and Movement: room for the development and learning of performing arts, perfectly equipped for these purposes. The Mirador: an original and high place that offers a perfect view of the main building of the Anahuacalli, ideal for photography and filming. Stone Forum: roofed outdoor space, in connection with volcanic stone. Ideal for activities with a reflective component that require reduced forum capacity. The Cube: a space with a minimalist, semi-open and multidisciplinary design, suitable for carrying out a variety of artistic activities. Creation: semi-open space for multiple uses, with a natural light entrance in a functionalist style. Experimentation: space equipped with water supply, for the development of artistic workshops and various events. Machines Forum: roofed outdoor space, in connection with the volcanic soil that is original to the place. Lola
