architecture, conceptualized by Frank Lloyd Wright (1867–1959),of a construction that is integrated with nature, which is typical of organic architecture. Lloyd Wright's work influenced that of O'Gorman, as well as the design projected by Rivera for the Anahuacalli, designed to achieve a balance between the pre-Hispanic and the modern. The Mexican architect considered Wright's work as the passage from a "servile veneration of European stupidity" to a confidence in the creative capacity of the American continent. The Anahuacalli's design is inspired by a teocalli, which means " gods’ house". It is built with volcanic stone from the eruption of the Xitle volcano; these rocks were extracteded from the same land where the museum was built. Its aesthetic includes symbolic and architectural elements that were originated in Mesoamerica. Accordingly, the main building of Anahuacalli is a manifestation of a spatial architectural perception that is characteristic in pre-Hispanic Mesoamerican constructions. The corners of the edifice are dedicated to an element of nature that is represented by original sculptures of their respective deities, according to the Mexica worldview. These divinities are Chicomecóatl (earth), Ehécatl Quetzalcóatl (wind), Tláloc (water), and Huehuetéotl (fire). The building has a total of twenty-three rooms distributed over three levels. In each of the rooms, stand out specific visual motifs of the pre-Hispanic mythology that so fascinated Diego Rivera. Facade The Anahuacalli is made up entirely of carved rock that originated from the eruption of the Xitle volcano. In the lower part of the main building, a platform of this same material protrudes, configuring a kind of "shelf" where pre-Columbian sculptures are installed. On that same level, we find the access to the museum that consists of an oval arch in front of the arrangement of elongated windows. These windows are made of amber-colored onyx stone, which looks opaque from the outside and translucent from the inside. These thin windows allow the passage of dim natural light; this is a sensible feature considering that the level where these windows are located represents the Underworld. On the part that is immediately upstairs the access level, the enormous windows that illuminate the interior of the intermediate floor stand out, among which two snake heads can be seen in the lower part of them. Likewise, the trapezoid-shaped roof is observed, reminiscent of ancient Mesoamerican structures. Interior of the building The ground floor of the Anahuacalli stands out for its complexity; it is made
