Built in the 16th century as a Jesuit college, this later became a prestigious teacher-training institute. In the 1920s, Rivera, Orozco, Siqueiros and others were brought in to do murals. Most of the work on the main patio is by Orozco; look for his portrait of Cortés and La Malinche underneath the staircase. The amphitheater, off the lobby, holds Rivera’s first mural, La Creación, undertaken upon his return from Europe in 1923. Mural tours (in Spanish) are given at noon and 4pm. Nowadays, the San Ildefonso hosts outstanding temporary exhibitions and houses the Salón Cinematográfico Fósforo of the national university.
