Diego Rivera Museum (Museo Anahuacalli) is off Av. División del Norte at Calle del Museo #150 (access is via Calle Arbol de Fuego). Designed by Rivera and constructed from dark volcanic stone, this imposing three-story structure with narrow walkways was built to house the artist's 39,000-piece collection of pre-Hispanic art.
Although you won't see any Rivera works, the building itself is an art form, replete with mosaic floors and ceilings depicting images of snakes and frogs (a Rivera trademark given that the artist's birthplace was Guanajuato, which means “place of frogs”). The art collection is remarkable. The objects on display include urns and decanters; stone, clay and marble pieces; smiling xoloitzcuintle dogs (a mid-size breed dating from pre-Hispanic times); and warriors and ceremonial ballplayers in full regalia.
Rivera also set up a studio on the upper floor of the building; mementos and works in progress now occupy the restored space. On clear days there are spectacular views from the building's hilltop location, particularly of twin volcanoes Popocatépetl and Iztaccíhuatl.
Note: The museum can be seen only on a docent-led guided tour Wednesday through Friday; all tours are given in Spanish. Weekend visits are self-guiding. Photography without flash is permitted.
