7. Sunset Park Salt Shed

Located by that water on 52nd Street in Sunset Park, a seemingly dilapidated building acts as a salt shed with a drop off zone to its side.
To give you a sense of its size, Flickr user -ytf- has made a stereoscopic 3D image of the shed, which offers a stunning view of its interior. To get the effect to work, the photographer says to sit two to three feet away and “gently cross your eyes.” You can view the full resolution photo here.
