From the Kingston Lounge:
Of all the forgotten and mysterious places in the Five Boroughs of New York City, few have histories as rich and interesting as that of North Brother Island. Situated in the Hell Gate, a particularly treacherous stretch of the East River, North Brother was home to the quarantine hospital that housed Typhoid Mary, was the final destination of the General Slocum during its tragic final voyage, and was the site of an experimental drug treatment program which failed due to corruption. Riverside Hospital, the name of the facility on the island throughout its various incarnations, treated everything from smallpox and leprosy to venereal disease and heroin addiction; after the Second World War, it housed soldiers who were studying under the GI bill. The entirety of the island has been abandoned since 1963; over a dozen buildings remain, in various states of disrepair.
