Between 1950 and 1952, Rivera built a giant tiled fountain to the Aztec rain god Tlaloc as part of an overhaul of Mexico City's municipal water system.
"It's a very special fountain. It's one of the most important sculptures that Diego Rivera did in his life," says Lilia Haua of Probosque Chapultepec, an organization that helped raise money to restore this work by Rivera.
