The City Below: The Secret Mapping of NYC's Subsurface
A talk uncovering New York City's hidden infrastructure — the tunnels, utilities, and underground geography most New Yorkers never see.
Why we picked this
Beneath Manhattan's grid lies a second city of tunnels, cables, and waterways that no single map has ever captured. This talk goes underground.
Beneath every block of New York City lies a tangle of infrastructure that has accumulated over centuries — subway tunnels, steam pipes, electrical conduits, water mains, pneumatic tubes, and forgotten passageways. No single comprehensive map of this subsurface world has ever existed, and the challenge of creating one is both an engineering puzzle and a historical excavation.
This talk at SVA Theatre explores the effort to document what lies beneath the city, combining urban geography, infrastructure history, and the practical realities of maintaining a metropolis built on top of itself. For anyone who has ever wondered what is happening beneath the sidewalk grate they just walked over.
