North Brother Island is in the East River between the Bronx and Rikers Island. It was used until the '40s as a quarantine hospital, but has been abandoned and closed to the public since then. Now it's a spectacular ruin.

Photographer Richard Nickel Jr. has dozens of gorgeous photos of the island and its various buildings up on his blog. He also has a fascinating history of the place and its most famous resident, Typhoid Mary, who died there in 1938.

The most arresting things are these images which show something beautiful that's gone to ruin and how nature can reclaim its space once humans leave it alone.
