Location: Roosevelt Island, New York City, NY
The Smallpox Hospital, often referred to as the Renwick Smallpox Hospital or the Renwick Ruin, is a historic Gothic Revival structure located at the southern tip of Roosevelt Island in Manhattan, New York City. Designed by renowned architect James Renwick Jr. and opened in 1856, it was the first major hospital in the United States dedicated to treating smallpox, a highly contagious and deadly disease that plagued humanity for millennia. Now a designated New York City Landmark and listed on the National Register of Historic Places, the hospital stands as a picturesque ruin, the only landmarked ruin in the city. Its haunting, ivy-covered facade, illuminated at night, evokes a romantic yet eerie mood, drawing comparisons to Gothic ruins like Tintern Abbey in England.
Smallpox, known as the “speckled monster,” was a devastating disease 
		with a mortality rate of up to 30% in unvaccinated populations. Before 
		Edward Jenner’s vaccine in 1796, it killed millions annually, including 
		monarchs like Louis XV of France and Queen Mary II of England, and left 
		survivors with severe scarring. Even after the vaccine’s introduction, 
		smallpox outbreaks persisted in New York City, particularly among 
		immigrants arriving at Ellis Island. By the mid-19th century, the city 
		faced recurring epidemics, with nearly 100 years of post-vaccine 
		outbreaks due to inconsistent vaccination efforts and urban crowding.
		
Prior to the Smallpox Hospital’s construction, smallpox patients on 
		Blackwell’s Island (Roosevelt Island’s name until 1921) were housed in 
		inadequate wooden shacks along the East River, described by Resident 
		Physician William Kelly as “a pile of poor wooden out houses”. The need 
		for a dedicated quarantine facility led to the hospital’s planning in 
		1850, with construction beginning on April 1, 1854, and completion in 
		1856. The hospital’s isolated location on the southern tip of 
		Blackwell’s Island, surrounded by water, was strategic, ensuring 
		quarantine by limiting access to ferries and keeping patients far from 
		Manhattan’s dense population.
The hospital was unique for its 
		time, admitting both charity patients, housed in wards on the lower 
		floors, and paying patients, who occupied private rooms on the upper 
		floors. This inclusivity reflected the severity of smallpox, which 
		necessitated isolating all infected individuals, regardless of 
		socioeconomic status. From 1856 to 1875, the hospital treated 
		approximately 7,000 patients annually, with a capacity of 100 beds. 
		Patients either recovered or died rapidly, resulting in high turnover.
		
In 1875, the hospital closed as a smallpox treatment facility due to 
		increasing population density on Blackwell’s Island and the 
		establishment of a new smallpox hospital on North Brother Island, which 
		offered greater isolation. The building was repurposed as the Home for 
		the Nurses and the Maternity and Charity Hospital Training School, 
		associated with the nearby Charity Hospital (later City Hospital). It 
		served as a nursing school until the early 1950s, when it was abandoned, 
		marking the beginning of its decline into ruin.
Designed by James Renwick Jr., the Smallpox Hospital is a striking 
		example of Gothic Revival architecture, a style Renwick favored early in 
		his career and also employed in landmarks like St. Patrick’s Cathedral 
		and Grace Church. The original structure, completed in 1856, measured 
		104 feet by 45 feet and was three stories tall, constructed with granite 
		gneiss (similar to schist) quarried from the island itself by prisoners 
		from the nearby Blackwell’s Island Penitentiary. This use of local 
		materials and labor kept construction costs low at $38,000.
		Architectural features included pointed-arch window openings, crenelated 
		parapets, and a central tower-like structure with recessed arches and 
		intricate Gothic detailing, creating a fortress-like appearance that 
		symbolized both containment and protection. The entrance featured a 
		heavy stone porch, and the third-floor windows had distinctive 
		triangular arches, adding to the building’s dramatic silhouette. The AIA 
		Guide to New York City describes the ruins as embodying “an eerie 
		romantic mood” and a “palpable documentation of a period in the past,” 
		evoking a sense of decayed grandeur.
In 1903–1905, two wings were 
		added to accommodate the growing nursing school: the south wing by York 
		& Sawyer and the north wing by Renwick, Aspinwall & Owen. These 
		additions matched Renwick’s original Gothic Revival style, maintaining 
		the building’s aesthetic uniformity. The wings, also built with 
		island-quarried stone, extended the hospital’s capacity but later 
		contributed to its structural instability when abandoned.
The 
		hospital’s design was not merely utilitarian; it was intended to inspire 
		awe and convey permanence, reflecting 19th-century ideals of 
		institutional architecture. However, its fortress-like appearance also 
		underscored its role in isolating patients, with no visitors allowed, 
		creating a sense of separation that patients may have felt keenly as 
		they gazed across the East River toward Manhattan.
After its abandonment in the early 1950s, the Smallpox Hospital fell 
		into disrepair. Vandals stripped metal detailing, and the roof 
		collapsed, leaving only the outer walls and foundation intact. By the 
		1970s, the building was a hollow shell, with vegetation, including vines 
		and red ivy, creeping over the facade, further destabilizing the 
		structure. A partial collapse of the north wing on December 26, 2007, 
		highlighted the urgency of preservation efforts.
The building’s 
		transformation into a ruin was both a loss and a new form of cultural 
		significance. In 1972, it was added to the National Register of Historic 
		Places, and in 1976, the New York City Landmarks Preservation Commission 
		designated it a city landmark, calling it “the only landmarked ruin in 
		New York City.” The commission speculated that it could become “the 
		American equivalent of the great Gothic ruins of England,” such as 
		Tintern Abbey, cherished for its picturesque decay. In the 1970s, 
		architect Giorgio Cavaglieri reinforced the walls to prevent total 
		collapse, and since 1995, the ruins have been illuminated nightly with 
		green floodlights, enhancing their eerie yet regal appearance and 
		raising awareness for preservation.
Today, the Smallpox Hospital stands as a roofless, windowless ruin, 
		surrounded by a reinforced fence to prevent public access due to safety 
		concerns. The interior is inaccessible, with no floors, ceilings, or 
		intact stairwells, and debris from collapses litters the site. The 
		exterior walls, covered in greenery, retain their Gothic Revival 
		features, though the north wing’s partial collapse and ongoing 
		deterioration pose challenges.
A $4.5 million stabilization 
		project, initiated in the 2000s, aimed to preserve the ruins and make 
		them publicly accessible. Walter B. Melvin Architects, retained in 2015, 
		conducted a multi-phase effort involving archival research, laser 
		scanning, condition surveys, and structural stabilization drawings. The 
		project includes plans to insert steel columns and reinforce walls, with 
		an estimated $1.2 million raised by the nonprofit Friends of the Ruin as 
		of 2022. The stabilization is tied to the development of Franklin D. 
		Roosevelt Four Freedoms Park, opened in 2012, which adjoins the hospital 
		site and envisions the ruins as part of a public park setting.
		Friends of the Ruin, founded in 2018, advocates for transforming the 
		site into a permanent memorial for frontline medical workers, 
		particularly those who fought COVID-19. The proposal leverages the 
		hospital’s history as a quarantine facility and nursing school to honor 
		healthcare professionals and commemorate pandemic resilience. The 
		envisioned memorial would include a landscaped public park, enhancing 
		the site’s waterfront tranquility and accessibility from all New York 
		boroughs. The project has gained traction post-COVID-19, as the pandemic 
		underscored the hospital’s relevance as a symbol of public health 
		struggles.
The Smallpox Hospital is more than a relic; it is a testament to New 
		York City’s public health history and the human cost of infectious 
		diseases. Its role as the nation’s first dedicated smallpox hospital 
		highlights early efforts to manage epidemics through quarantine, a 
		practice that resonates with modern responses to pandemics like 
		COVID-19. The hospital’s dual function as a nursing school from 1875 to 
		the 1950s underscores its contribution to medical education, training 
		generations of nurses who served on the frontlines.
The ruins 
		also reflect the darker aspects of 19th-century urban policy. Roosevelt 
		Island, formerly Blackwell’s Island, was a place of exile for the city’s 
		“undesirable” populations—prisoners, the poor, the sick, and the 
		mentally ill. The hospital’s construction by penitentiary inmates and 
		its isolation from Manhattan symbolize the era’s approach to warehousing 
		the marginalized. As one X post speculates, the hospital’s imposing 
		structure may hint at an “ancient repurposed building,” though this 
		lacks evidence and likely reflects romanticized views of its Gothic 
		aesthetic.
The ruins’ landmark status and their portrayal in 
		media, such as Unforgotten Films’ short documentaries, emphasize their 
		cultural value. The 2024 film by artist Aaron Asis, in partnership with 
		the New York Landmark Conservancy, offers rare interior glimpses and 
		advocates for preservation, highlighting the site’s potential for 
		adaptive reuse. Visitors, including students from Williamsburg High 
		School for Architecture and Design, describe the ruins as a “poignant 
		reminder” of medical history, with their greenery-covered walls evoking 
		both decay and resilience.
The Smallpox Hospital is located in Southpoint Park, adjacent to 
		Franklin D. Roosevelt Four Freedoms Park, at the southern tip of 
		Roosevelt Island. It is accessible via the F train to the Roosevelt 
		Island station, the Roosevelt Island Tramway from Manhattan (payable 
		with a MetroCard), or ferries from Astoria, Long Island City, or Wall 
		Street. Visitors can walk south along West Road to E Road, where the 
		ruins are visible behind a fence. The site offers stunning views of 
		Manhattan’s skyline and the Queensboro Bridge, contrasting the ruins’ 
		decay with the city’s modernity.
The ruins are not open for 
		interior tours due to structural instability, but the exterior can be 
		viewed year-round. The nightly illumination creates a striking nighttime 
		experience, though some describe it as “creepy” or “haunted”. A visit 
		typically takes 30–60 minutes, often combined with exploring Four 
		Freedoms Park or the island’s other historic sites, such as the 
		Blackwell House or the Octagon. The island’s free Red Bus provides 
		hop-on, hop-off service, enhancing accessibility.
Tripadvisor 
		reviews praise the site’s historical significance and scenic setting, 
		recommending it for those interested in medical history or seeking a 
		quieter alternative to Manhattan’s bustle. However, some note the ruins’ 
		inaccessibility and dilapidated state as limitations, suggesting more 
		interpretive signage or stabilization to enhance the experience.
Preserving the Smallpox Hospital poses significant challenges. Its 
		advanced decay, exacerbated by the 2007 collapse and ongoing erosion, 
		requires costly stabilization. The $4.5 million project, while 
		ambitious, faces funding hurdles, with Friends of the Ruin relying on 
		private and public donations. Some argue the ruins should be demolished 
		to make way for revenue-generating development, citing their limited 
		practical use and maintenance costs. Others, including preservationists 
		and historians, counter that the ruins are a unique artifact of New 
		York’s medical and architectural heritage, irreplaceable as a site of 
		reflection and education.
The memorial proposal has sparked 
		debate. While many support honoring healthcare workers, some question 
		whether a ruin can adequately serve as a public space without 
		significant reconstruction, which could alter its historic character. 
		Additionally, the site’s isolation, while historically functional, 
		limits its visibility compared to more central memorials.
The 
		hospital’s Gothic aesthetic and abandoned state have fueled speculative 
		narratives, including rumors of hauntings or its use in fictional 
		settings like “Gothic romances”. Such romanticization risks 
		overshadowing the real suffering of smallpox patients and the labor of 
		inmates who built it, a tension preservationists must navigate.
The Smallpox Hospital’s significance lies in its layered history: a 
		pioneering medical facility, a training ground for nurses, and a symbol 
		of 19th-century attitudes toward disease and marginalization. Its Gothic 
		Revival design, while beautiful, served a grim purpose, isolating 
		patients in a fortress-like structure that reflected both care and 
		control. The ruins’ current state—decayed yet preserved—mirrors the 
		paradox of commemorating a disease eradicated in 1980 while grappling 
		with modern pandemics like COVID-19.
Critically, the hospital’s 
		narrative is incomplete without acknowledging the Wampanoag and other 
		Indigenous populations decimated by smallpox, often deliberately through 
		colonial practices like distributing infected blankets, as noted during 
		the French and Indian Wars. While the museum at Plimoth Patuxet 
		addresses this broader context, the Smallpox Hospital’s interpretation 
		focuses narrowly on its 19th-century role, missing an opportunity to 
		connect to these earlier histories.
The preservation effort, 
		while laudable, raises questions about authenticity. Stabilizing the 
		ruins with modern materials like steel columns risks diminishing their 
		“romantic decay,” a quality praised by the Landmarks Preservation 
		Commission. Conversely, allowing further deterioration could erase a 
		tangible link to the past. The memorial proposal, though compelling, 
		must balance historical integrity with contemporary relevance, ensuring 
		the site remains a place of education rather than mere spectacle.
