This small museum is set in a historic waterworks building on the edge of Chapultepec. Its main draw is Diego Rivera's unusual water-themed mural, which combines painted surfaces, tile work, and a sculptural element rather than behaving like a conventional wall painting.
The museum is a short, focused visit rather than a major Chapultepec stop, but it is worthwhile for Rivera fans and anyone interested in Mexico City's water infrastructure and public art.
