Gizmodo reports:

It’s a place where few living New Yorkers have ever set foot, but nearly a million dead ones reside: Hart Island, the United States’ largest mass grave, which has been closed to the public for 35 years. It is difficult to visit and off-limits to photographers. But that may be about to change, as a debate roils over the city’s treatment of the unclaimed dead. Never heard of Hart? You’re not alone—and that’s part of the problem.

Hart Island is a thin, half-mile long blip of land at the yawning mouth of Long Island Sound, just across the water from City Island in the Bronx. Depending on who you ask, it was named either for its organ-like shape or for the deer (or hart) that thrived here after trekking across the frozen sound in the 18th century. Hart is dense with history; it’s been used as a prison for Confederate soldiers, a workhouse for the poor, a women’s asylum, and a Nike missile base during the Cold War.

Its most important role has been to serve as what’s known as a potter’s field, a common gravesite for the city’s unknown dead. Some 900,000 New Yorkers (or adopted New Yorkers) are buried here; hauntingly, the majority are interred by prisoners from Riker’s Island who earn 50 cents an hour digging gravesites and stacking simple wooden boxes in groups of 150 adults and 1,000 infants. These inmates—most of them very young, serving out short sentences—are responsible for building the only memorials on Hart Island: Handmade crosses made of twigs and small offerings of fruit and candy left behind when a grave is finished.
