North Brother Island Quarantine Zone, New York: quarantine zone, leper colony and centre for drug addicts. Just 350 yards from the crowded tenements of the Bronx, North Brother Island was first employed as a quarantine centre in 1885. Closed in 1963, it is now a haunting labyrinth of crumbling ruins.
Berkyn Manor, Berkshire, UK | Also known as Bull Manor, has been in a state of decay since the last resident, Ernest Raymer, died in 1987 at the age of 96. It's interesting that many remnants left out are simple items, such as newspapers and letters, from the early-mid 20th century; making it appear at first glance that the home has been uninhabited for much longer. The property has existed since the 1630s, although the manor was rebuilt in 1848.
