New York City Underground – lost underground tunnels beneath the city see new light

You would presume that city government would have knowledge of every nook and cranny in their city, that they would have every street, subway, tunnel, and building mapped and documented. Surprisingly, many of our older cities have underground labyrinths that are largely or wholly undocumented, long forgotten by time. In New York City, it is believed that thousands of miles of underground tunnels exist, some of which have not seen a human’s presence in over 150 years.
