Invisible New York is a photographic exploration of the hidden and often abandoned infrastructure of New York City. Inaccessible and unknown to most New Yorkers, the structures and machinery captured in Stanley Greenberg's luminous black-and-white prints deliver the essential services that a city's inhabitants usually take for granted. Many of these vast and imposing facilities have in recent decades been neglected or fallen into disuse, whereas others remain intact and in continuous use. Greenberg's dark and poetic images document how a city works, its technological evolution since the nineteenth century, and the toll that deterioration and years of deferred maintenance can take on the soul of a city.
