Beneath the chaos of Manhattan’s streets lies another city—silent, forgotten, and carved in brick and stone. A labyrinth of hidden tunnels snakes beneath old New York, built for subways, smugglers, secret societies, and stories no one was supposed to find.

In this episode of Disturbing History, Brian takes us deep under the surface to explore the eerie and often overlooked world beneath the Big Apple. From Prohibition-era escape routes and underground speakeasies to sealed-off subway stations and Masonic passageways, these tunnels have carried more than just trains—they’ve carried whispers, rumors, and secrets.Who built them?
Why were so many erased from maps?

And what still lingers down there, untouched by time and light? Some cities grow upward.

Others grow outward.

But New York?

It’s always been growing downward—into mystery. Because sometimes, what we pave over…
was never meant to be uncovered.
