"Diego Rivera's & Frida Kahlo's Gift to Mexico They intended it as their gift to Mexico , and what a gift it is. Diego Rivera and Frida Kahlo, two of the most famous artists of the 20th century, worked with renowned Mexican architect Juan O'Gorman to create Museo Anahuacalli, a temple-like structure that houses the 50,000+ pre-Hispanic objects Rivera collected during his lifetime. The museum, whose design was also influenced by Frank Lloyd Wright and his notions about the role of the physical environmental in the conceptualization and construction of buildings, also showcases hundreds of pieces of artisan and craft works representative of Mexico. Note that the museum is not open on Monday or Tuesday."
