Old Croton Aqueduct, Gate Chamber
Manhattan, NYC

 

The Old Croton Aqueduct supplied New York City's fresh water from the 1840s until early in the 20th century. It was the largest engineering project that had ever been undertaken in the United States when it was built in the 1840s. It was taken completely out of service by 1950, and today much of the 40-mile tunnel stands empty, inaccessible, and forgotten underground.
