"This historic but infrequently-visited site was constructed in 1951 as a hydraulic water system connected to the city's main water lines. It no longer acts as a municipal water work but rather a museum and cultural landmark, underscoring the city's complicated relationship with water. In the lesser-traveled section of Chapultepec, it is currently under renovation and closed to the public, though the massive Rivera sculpture of the Azteca water god Tlaloc out front can still be admired. The building was designed by architect Ricardo Rivas and would be worth a visit in its own right but is made even more appealing by a sprawling Diego Rivera mural that was originally under water! Drained and water diverted, the murals are even more show-stopping. A kooky mix of mid-century public works and contemporary art live here in the city's green lung." - Scarlett Lindeman
