North Brother Island

Location: East River Map

Area: 20.12 acres (81,400 m2)

 

North Brother Island is a small, uninhabited island (about 20 acres) in New York City's East River, between the Bronx and Rikers Island, near the treacherous Hell Gate strait. It is now a protected bird sanctuary (part of the Harbor Herons Preserve) and is strictly off-limits to the public due to hazardous ruins and ecological sensitivity.
Its history spans from colonial times through quarantine, tragedy, and abandonment, making it one of NYC's most haunting and forbidden places.

 

History

Early History (17th–19th Centuries)
Dutch explorers claimed the island (along with the smaller South Brother Island) in 1614 as part of the Dutch West India Company holdings. They named the pair De Gesellen ("the companions" or "the brethren"). The islands were later under British control. In 1695, they were granted to James Graham, but treacherous currents limited development.
In the late 18th century, the "Two Brothers" islands were auctioned (e.g., in 1791 at the Merchants' Coffee House) and described with some structures like a dwelling, barn, and orchard on North Brother. Ownership remained private for much of the 19th century. North Brother was initially part of Westchester County (via the Bronx) before transfers to New York City jurisdiction in 1881.
A lighthouse was built in 1869 (after earlier failed attempts) on the southern tip to aid navigation through Hell Gate's dangerous waters, which had wrecked many ships. This was one of the first permanent structures. The keeper, sometimes referred to in lore as "Lighthouse Dan," lived there in relative isolation.

Riverside Hospital and Quarantine Era (1880s–1940s)
In the mid-1880s, the city established Riverside Hospital on North Brother Island by relocating it from Blackwell's Island (now Roosevelt Island). The goal was to isolate and treat patients with highly contagious diseases like smallpox, typhoid, tuberculosis, typhus, yellow fever, and later polio (notably during the 1916 epidemic).
The hospital opened around 1885, with buildings constructed over time (oldest in 1885; Tuberculosis Pavilion as late as 1943). It included pavilions for specific illnesses, laboratories, staff housing, dormitories, and other facilities—eventually about 25 buildings. The island's isolation was seen as a public health success, protecting the dense city from outbreaks, though practices involved forced quarantines that disproportionately affected poorer and immigrant communities.
Photographer and social reformer Jacob Riis documented the island in the 1890s, capturing images of the hospital, lighthouse, and "coffin corner" (a grim area associated with the dead).
The General Slocum Disaster (1904): On June 15, 1904, the paddle steamer General Slocum caught fire while carrying over 1,300 German-American passengers (mostly women and children from St. Mark's Evangelical Lutheran Church) on a picnic outing. Faulty life-saving equipment, panic, and the captain's decisions led to the ship beaching near the island. Over 1,000 people died from fire, drowning, or related causes—the deadliest disaster in NYC history until 9/11. Hospital staff helped rescue survivors, and bodies washed ashore. The tragedy devastated the Lower East Side's German community.
Typhoid Mary (Mary Mallon): The island's most famous resident was Mary Mallon, an Irish immigrant cook and the first known asymptomatic carrier of typhoid fever in the U.S. She infected dozens (estimates vary; at least 122 people, with several deaths) through her work in wealthy households. First quarantined on the island from 1907–1910, she was released on the condition she not cook but violated it (under an alias), causing more outbreaks. She was forcibly returned in 1915 and lived there (in a small cottage) until her death from pneumonia in 1938, after over two decades of isolation. She maintained she was unfairly targeted. Her case highlighted tensions around public health, civil liberties, and immigration.
The hospital declined in necessity by the 1930s–1940s as medical advances (e.g., vaccines and antibiotics) reduced the need for mass quarantines.

Post-WWII and Later Uses (1940s–1960s)
After WWII, the island housed returning veterans and their families as student housing amid a housing shortage. A small community of up to ~500–1,500 people emerged, with amenities like a grocery store, library, and movie theater. A ferry shuttled residents to the mainland for work or classes. It was described as idyllic by some former residents.
In 1952, it was repurposed as a pioneering (but controversial) drug rehabilitation center for adolescent heroin addicts—the first of its kind offering treatment, rehab, and education. Patients faced isolation, locked rooms, and harsh conditions; graffiti from this era remains visible. Issues like staff corruption, high costs, and patient resentment led to closure in 1963–1964. It reportedly inspired the play Does a Tiger Wear a Necktie? (which boosted Al Pacino's career).

Abandonment and Current Status (1960s–Present)
The island was abandoned after 1964. Various proposals followed—selling it, using it for homeless housing, extending Rikers Island jail, or even casinos ("Vegas of the East")—but none materialized. It became overgrown, with ruins decaying amid dense vegetation (including invasive species like kudzu).
In 2007, the federal government (with partners like the Trust for Public Land) acquired it and transferred control to NYC. It is managed by the NYC Department of Parks & Recreation as a "Forever Wild" site and bird sanctuary, vital for herons, egrets, and other wading birds. Public access is prohibited except for rare academic/scientific permits escorted by staff, due to collapsing buildings, hazards (e.g., open manholes, poison ivy), and wildlife protection.
A 2014–2016 study explored limited public access, but costs and risks halted progress. Occasional visits by journalists or researchers (e.g., 2017) highlight its eerie beauty and dangers. A structure fire occurred in 2025.
Today, North Brother Island stands as a time capsule of NYC's public health history, maritime tragedies, and urban wilderness—its ruins slowly reclaimed by nature just miles from one of the world's busiest cities. Books like North Brother Island: The Last Unknown Place in New York City (by Christopher Payne and Randall Mason) and resources from the Bowery Boys provide deeper dives with photos and details.

 

Architecture

Historical Development and Overall Layout
The island saw limited early use, including a lighthouse constructed in 1869 (the first permanent structure). Significant development began in the mid-1880s after the City of New York purchased it around 1880–1885 to relocate Riverside Hospital from Blackwell's (now Roosevelt) Island. The facility treated smallpox, typhoid (famously Typhoid Mary, quarantined there until her death in 1938), tuberculosis, typhus, polio, and other diseases.
Early phase (1880s): Architect George B. Post or related plans (sometimes associated with the Haight Plan) featured a cohesive network of mostly brick structures centered on the northwest shore near a large dock. Wood-frame pavilions radiated outward in a half-circle from a central building for isolation. Sanborn maps from 1885 show this layout. The first building was the c. 1885 Male Dormitory (a pavilion). Other early structures included an ice house, boiler room, storehouse, and about five heated pavilions spaced ~50 feet apart for ventilation.
Expansion: Over decades, the complex grew to around 25–32 buildings, including support infrastructure for a self-contained community (power plant, morgue, chapel, staff housing, recreation like tennis courts). The last major addition was the Tuberculosis Pavilion (cornerstone 1941, opened ~1943), a four-story structure by architect Electus D. Litchfield.
Later uses: Post-WWII (1946–1951) as veterans' housing; 1951–1963 as a juvenile drug rehabilitation center (repurposing isolation features). Closed in the mid-1960s and abandoned, with ~25 buildings remaining in extreme dilapidation by the 21st century.

The island has a concrete seawall (breached in places, contributing to erosion), paved roads (now overgrown), fire hydrants, lampposts, and utility remnants. Buildings are spread somewhat randomly but clustered around former functional zones, now densely overgrown with invasive vegetation (vines, trees growing through structures).

Key Buildings and Architectural Styles
Most surviving structures are red brick with limestone or simple detailing, typical of late-19th/early-20th-century institutional architecture—practical, durable, and designed for hygiene/isolation rather than ornament. Wood-frame elements were earlier and more perishable. Styles mix Victorian/Queen Anne influences in early pavilions with more modernist or utilitarian mid-20th-century forms.

Tuberculosis Pavilion (c. 1943, largest/most prominent): A multi-story (four-story) brick building with long, narrow wards featuring extensive rows of windows for maximum light and fresh air circulation (a key TB treatment principle pre-antibiotics). Steeply gabled or flat roofs, institutional scale. Now heavily ruined—roofs collapsing, trees/vines overtaking interiors, creating a haunting, cathedral-like atmosphere amid tall trees. Interiors once included dormitory wards with visible doors and frames.
Male Dormitory/Pavilions (c. 1885): One-story (or low-rise) wood-frame or early brick isolation pavilions. Long and narrow for cross-ventilation and patient separation. The male dormitory is among the oldest and has served as a reference for early layouts. Several similar pavilions existed; remnants show simple, functional design.
Nurse’s Residence/Home: Substantial brick building with domestic/institutional hybrid features. Visible in street views; interiors included bathrooms and living spaces. Part of staff housing cluster.
Physician’s Home / Staff Houses / Doctor’s Quarters: More residential in character—brick with details like gables, dormers, or porches. One (Physician’s Home) was noted for potential adaptive reuse. Warm red brick, limestone accents, steeply gabled roofs with copper dormers in some descriptions.
Boiler House / Power Plant / Coal House / Smokestacks: Industrial utility buildings with prominent brick smokestacks (highly visible from the Bronx shore). Coal storage and boiler rooms supported the self-sufficient campus. Now ruined, with kudzu and vegetation overtaking.
Morgue: Functional brick structure near the boiler area; part of the grim infrastructure of a quarantine hospital.
Chapel (St. John-by-the-Sea Church): Modest religious building with front and side views showing simple ecclesiastical architecture.
Administration / Service Buildings / Kitchen / Storehouse: Support structures, including a kitchen/staff house. Varied in scale; some incorporated into later uses.
Lighthouse (1869): On the southern tip (federal portion). Originally a square wooden keeper’s residence with an octagonal tower and mansard roof. One of the earliest structures; later iterations existed.

Other features included docks/gantries for ferry access, a school, recreation areas, laboratories, isolation cottages, and utility vaults.

Current State and Architectural Significance
Today, the buildings are in advanced decay: roofs gone or failing, walls crumbling, interiors exposed to elements, and nature (trees through windows, vines, dense forest) dominating. This creates a powerful "ruins aesthetic"—eerie yet beautiful, symbolizing nature's reclamation. Hazards include collapse risks, poison ivy, and overgrowth; public access is strictly limited (mostly for research or ecological reasons; it's a key heron nesting site).
Architecturally, the island illustrates evolving public health and institutional design: from pavilion plans promoting airflow (influenced by miasma theory transitioning to germ theory) to consolidated brick facilities. It represents broader NYC history—quarantine, immigration/public health responses, and 20th-century social programs—within a rare, largely intact (if ruined) ensemble. Preservation efforts (e.g., University of Pennsylvania studies) have assessed stabilization, balancing ecology and heritage.
Photographers like Christopher Payne have documented its seasonal transformations, highlighting lost infrastructure (buried streets, hydrants) beneath the greenery. Historical photos show a tidy, bustling campus contrasting today's wild state.

 

Typhoid Mary

 

Early Life and Immigration
Mary Mallon was born in Cookstown, County Tyrone, Ireland (then part of the UK). Little is known about her early education, but she had some schooling. At around age 15 in 1883 (or 1884 in some accounts), she emigrated to the United States aboard the steamship Ethiopia. She initially lived with an aunt in New York City and soon found work as a domestic servant, primarily as a cook for wealthy families. She earned a good reputation for her cooking skills and wages, which was notable for an unmarried Irish immigrant woman at the time. Her career involved both live-in positions and moving between households.

Career as a Cook and Early Outbreaks (1897–1906)
Between 1897 and 1907, Mallon worked for several affluent New York families and households, often in summer homes on Long Island or elsewhere. Typhoid fever outbreaks followed her path in multiple instances, though connections were not immediately obvious. Typhoid fever, caused by the bacterium Salmonella enterica serotype Typhi, spreads through contaminated food or water handled by carriers. It causes high fever, weakness, abdominal pain, and can be fatal without treatment. Mallon was a "healthy carrier"—infected but asymptomatic, with the bacteria likely harbored in her gallbladder.
Key early incidents included:

Households in Mamaroneck, New York; a family in New York City (laundress affected); the Drayton family in Dark Harbor, Maine (multiple family members and staff ill, but Mallon helped nurse them); Sands Point (staff affected); and others.
In 1906, she worked for banker Charles Henry Warren's family in Oyster Bay, Long Island. Six of eleven people fell ill shortly after she started. The property owner hired sanitary engineer and epidemiologist George Soper to investigate.

Soper traced the outbreaks to Mallon after mapping her employment history. He eliminated other common sources (water, milk, etc.) and noted her role in preparing items like peach ice cream, which could transmit the bacteria if contaminated. She had worked for eight families, with seven experiencing typhoid cases. Soper identified around 26 cases linked to her at that point.

Discovery, Resistance, and First Quarantine (1907–1910)
In early 1907, while Mallon worked for the Walter Bowen family on Park Avenue in Manhattan, more cases emerged, including the death of Bowen's daughter. Soper confronted her, requesting blood, urine, and stool samples. Mallon reacted angrily, brandishing a carving fork and chasing him away. She firmly denied being ill or a carrier, viewing the accusations as persecution.
Health officials, including Dr. Sara Josephine Baker, eventually involved police. Mallon resisted arrest fiercely—hiding in a shed and fighting back—before being taken to Willard Parker Hospital. Tests confirmed high levels of typhoid bacilli in her stool. She refused treatments like gallbladder removal. She was transferred to Riverside Hospital on North Brother Island, a quarantine facility for contagious diseases in the East River between the Bronx and Rikers Island.
On the island (about 16–20 acres), she lived in a small cottage, had some freedom to walk around, and access to facilities like the chapel. She was not entirely isolated from care but felt like "a leper." She sued for release in 1909, arguing violations of her rights, but lost in court (the balance favored public safety). After about three years, she was released in 1910 on the condition that she not work as a cook, report regularly to health authorities, and use good hygiene.

Release, Relapse, and Second Quarantine (1910–1938)
Mallon tried to comply at first, working in a laundry (lower pay). But cooking was her skilled profession and source of better income. She changed her name to Mary Brown and resumed cooking, leading to more outbreaks.
In 1915, a major outbreak hit Sloane Maternity Hospital in Manhattan (25 cases, 2 deaths), where she worked under an alias. She was tracked down (reportedly in Westchester County) and forcibly returned to North Brother Island. This second quarantine lasted until her death—over 23 years.
On the island, she lived relatively quietly. She reportedly worked washing lab bottles and glassware. She suffered a paralytic stroke in 1932, which led to a slow decline. She died of pneumonia on November 11, 1938, at age 69, still on North Brother Island. She was buried at Saint Raymond's Cemetery in the Bronx.

 

Local legends

The island's reputation as haunted or cursed stems directly from its grim uses:
Quarantine Hospital (Riverside Hospital, late 1800s onward): Relocated here to isolate patients with highly contagious diseases like smallpox, tuberculosis, typhus, and yellow fever. Conditions were often dire—overcrowding led to patients in tents, food shortages, and inadequate heating. Many died and were handled in an on-site morgue. Patients were sometimes held against their will with limited contact to the outside world.
Typhoid Mary (Mary Mallon): The most famous resident. An Irish immigrant and asymptomatic carrier of typhoid fever, she infected dozens (estimates 51–122 people, with several deaths) while working as a cook. Quarantined on the island twice (1907–1910 and 1915–1938), she lived in a cottage, worked as a lab technician, and died there of pneumonia in 1938. She vehemently denied being a carrier and resisted treatment (e.g., gallbladder removal). Her story of forced isolation has become legendary, symbolizing tensions between public health and individual rights.
General Slocum Disaster (June 15, 1904): One of NYC's deadliest tragedies before 9/11. The paddle steamer General Slocum, carrying ~1,300–1,400 mostly German-American women and children on a church picnic, caught fire in the East River. Faulty lifeboats, rotten life vests, and poor crew response led to panic. Captain beached it on North Brother Island, but over 1,000 died (many by drowning or burning; many couldn't swim). Hospital staff and patients heroically rescued survivors and recovered bodies that washed ashore. The event devastated the community and is often linked to ghostly maritime apparitions.

Later uses included housing for WWII veterans and a controversial 1950s–1960s drug rehab for adolescent heroin addicts (closed amid corruption reports). The island has been abandoned since the mid-1960s, with ~25 buildings now in extreme disrepair, overtaken by nature.

Key Local Legends and Hauntings
The combination of mass death, forced quarantine, disease, and isolation has produced rich oral and paranormal folklore:
Screams and Voices from the Ruins: Visitors and those viewing from boats or shore report hearing screams, cries, and pleas emanating from the middle of the island or the crumbling Riverside Hospital buildings—especially at night. These are often attributed to dying patients, Slocum victims, or quarantined individuals. Some distinguish them from distant Rikers Island prison noise.
Apparitions and Hospital Gowns: Ghostly figures in hospital attire or period clothing are said to wander the shores or ruins. Whispers, unexplained movements, shadow figures, and glowing orbs are commonly reported by urban explorers. Some claim to see remnants of the General Slocum or spirits along the water's edge.
Cursed or Haunted Island Overall: Many locals and paranormal accounts describe the island as inherently cursed due to its "spotty history" of suffering, exile, and death. The morgue, forced quarantines (where patients sometimes vanished from public view), and tragic shipwrecks amplify this. The forbidden status and decaying structures enhance the sense of lingering unrest.
Typhoid Mary Lore: Her restless spirit is sometimes invoked in tales of the island. As a symbol of unwilling captivity and denial, legends portray her presence as a lingering force tied to disease and isolation. Her story has mythologized her into a near-supernatural figure in NYC folklore.
Maritime and Rescue Ghosts: Apparitions linked to the General Slocum (bodies on the beach, desperate swimmers) and earlier shipwrecks in Hell Gate add layers. Heroic rescuers or victims are said to appear in visions.

These stories circulate in ghost tours, urban exploration communities, podcasts, Instagram/TikTok videos, and books like North Brother Island: The Last Unknown Place in New York City. The island's inaccessibility turns it into a modern urban legend hotspot—similar to other forbidden or tragic NYC sites.

Modern Context and Bird Sanctuary
Today, the island is a thriving sanctuary for birds like black-crowned night herons, creating a stark contrast: life reclaiming a place of death. This "eerie but beautiful" juxtaposition (overgrown ruins amid flourishing nature) adds to the folklore—some see it as nature reclaiming a cursed site.
Note: Trespassing is illegal and highly dangerous due to unstable buildings. Legends are best explored through historical accounts, virtual views, or guided ghost tours rather than risky visits. The stories endure because they blend verifiable tragedy with the human tendency to imagine unrest in places of profound suffering.
