North Brother Island: New York City’s Forbidden Wilderness
North Brother Island, located in the East River between the Bronx and Rikers Island, remains off-limits to the public due to its hazardous, decaying infrastructure and its status as a protected bird sanctuary. Owned by the City of New York, the 20-acre landmass is managed by the New York City Department of Parks and Recreation, which prohibits unauthorized access to preserve the island’s ecological stability and public safety.
Why is North Brother Island restricted?
Public access is prohibited primarily because the island’s structures are structurally unsound. According to the New York City Department of Parks and Recreation, the site contains the ruins of the former Riverside Hospital, which operated from the late 19th century through the mid-20th century. Decades of abandonment have left these buildings in an advanced state of collapse. Beyond the physical danger, the island serves as a vital nesting ground for the black-crowned night heron and other migratory birds. The New York City Planning Department notes that the island is managed strictly as a wildlife habitat, and any human intrusion would disrupt these sensitive nesting colonies.
What is the history of the island’s facilities?
The island’s most prominent history involves its use as a medical quarantine facility. In 1885, the city moved the Riverside Hospital there to isolate patients suffering from smallpox, and later, tuberculosis. Perhaps most famously, the island housed “Typhoid Mary” Mallon, a chronic carrier of typhoid fever, who was confined there for over two decades until her death in 1938. After World War II, the island was repurposed to provide housing for veterans and their families, and later served as a treatment center for adolescent drug addicts. These programs eventually shuttered in the early 1960s, leading to the island’s permanent abandonment.
How does the island compare to other New York City sites?
Unlike other island parks in New York City, such as Governors Island or Roosevelt Island, North Brother Island has never undergone a large-scale redevelopment process. The following table highlights the differences in status between these locations:
| Location | Current Primary Status | Public Access |
|---|---|---|
| Governors Island | Public Park and Cultural Hub | Open |
| Roosevelt Island | Residential and Institutional | Open |
| North Brother Island | Protected Wildlife Sanctuary | Closed |
Can the public ever visit?
There are no public ferry services or legal entry points for civilians. While historians, researchers, and photographers have occasionally been granted rare, escorted access for documentation purposes, the general public cannot visit. The NYC Parks Department maintains a strict policy of non-entry to prevent vandalism, protect the fragile ruins, and ensure the safety of visitors who might otherwise be injured by falling debris or uneven, overgrown terrain.
Key Takeaways
- Status: The island is a restricted wildlife sanctuary owned by the City of New York.
- Safety: Decaying hospital buildings pose significant risks to any unauthorized visitors.
- Ecology: The site is a protected habitat for the black-crowned night heron.
- History: It served as a quarantine hospital and a post-war housing site before being permanently vacated in 1963.
As of today, the city has no plans to open the island for public recreation. Its future remains tethered to its role as a quiet, human-free refuge within the dense urban landscape of the East River.
