6. Mariner’s Marsh

Mariner’s March on Staten Island is a place even the NYC Parks Department describes on their sign as “eerie.” Located just next to the New York Container Park, the forsaken and abandoned landscape was once the bustling Milliken Brother’s Structural Iron Works and later a shipyard that produced warships.

The marsh is overtaken by freshwater ponds and is littered with abandoned cars, boat hulls, and disintegrating piers that serve as a vague reminder of what the site once was. Adding to its elusiveness, though it has been operated by the parks department since its acquisition in 1997, it has been closed to the public for an environmental investigation since 2006
