Two groups of immigrants made the South Bronx their own. They arrived a century apart. They worked the same streets, raised families in the same buildings, and built communities that survive today. This is the story of the Irish and Puerto Rican South Bronx.

The Irish Arrive: Building a Neighbourhood From Nothing
The Irish came first. They crossed the Harlem River in the 1840s and 1850s. They were running from the Famine. They were looking for work.
They found both in the South Bronx. Factories lined the Harlem River waterfront. Ironworks, gasworks, and brickyards employed thousands. The work was hard and dangerous. But it paid wages. That was enough.
By the late 1800s, the South Bronx had a thriving Irish-American community. Mott Haven, Melrose, and Longwood were filled with Irish families. They built churches. They formed mutual aid societies. They sent their children to parochial schools.
The neighbourhood around Kelly Street became an Irish stronghold. Row houses and tenements packed in entire extended families. Whole blocks shared the same surnames. You could walk from one end of the street to the other and speak only to cousins.
St. Jerome’s Parish, founded in 1898 in Mott Haven, anchored the Irish Catholic community for decades. The church still stands today on Alexander Avenue. It is one of the oldest surviving institutions in the South Bronx.
The Irish weren’t alone for long. German Jews, Italians, and Eastern Europeans also settled in the area. But it was the Irish who shaped the character of the early South Bronx. They built its political organisations. They staffed its police stations and firehouses. They dug its subway tunnels.
The Irish had already built a world in Lower Manhattan. The South Bronx was their second chapter.
The Great Migration North: Puerto Rico Meets the Bronx
Everything changed after the Second World War. Cheap airfares opened up. A one-way flight from San Juan to New York cost less than a month’s wages. Hundreds of thousands of Puerto Ricans made the journey.
Puerto Ricans were US citizens. They needed no visa. No quota. No inspection at Ellis Island. They stepped off the plane at Idlewild Airport and were immediately New Yorkers.
They moved first to East Harlem — El Barrio. Then to the South Bronx. By the 1950s, the Bronx had the largest Puerto Rican population outside of Puerto Rico itself.
They filled the apartments that Irish families were leaving. The Irish had saved enough to move to the suburbs. The South Bronx was becoming too crowded. Too loud. Too different from what they had known.
The Puerto Ricans transformed what they found. Bodegas replaced corner groceries. Salsa music drifted from open windows. Spanish mixed with English on every block. The South Bronx became something new. It became something uniquely its own.

Life in the South Bronx: What the Photographs Don’t Show
The tenements were crowded. A two-room apartment might hold eight people. Cousins slept on floors. Grandmothers shared beds with grandchildren.
But they were also alive. Roof parties in summer. Stickball games in the street. Mothers calling children home from fire escapes. The smell of rice and beans from every floor.
Lincoln Hospital in Mott Haven was the community’s lifeline. It opened in 1839. It had served the poor for over a century. By the 1960s, it was the primary hospital for a neighbourhood with almost no other medical care.
The Young Lords understood the stakes. This Puerto Rican civil rights organisation seized the hospital briefly in 1970. They demanded better services. Better conditions. A community board with real power.
Their protest worked. Lincoln Hospital received major investment. Today it remains one of the most important public hospitals in the Bronx.
Colin Powell grew up on Kelly Street in the South Bronx. He was the son of Jamaican immigrants. He played on the same streets where Irish kids had played a generation before. He attended Morris High School. He went on to become the first African American Chairman of the Joint Chiefs of Staff.
That is the South Bronx. It takes in whoever arrives. It shapes them. It sends them out into the world carrying something of itself.
The Fires That Burned the Bronx
The 1970s nearly destroyed everything. Landlords abandoned their buildings. Families were left with no heat, no hot water, no repairs. Some landlords set fires to collect insurance money.
Between 1970 and 1980, the South Bronx lost 80,000 housing units. Entire blocks burned to the ground. Photographs from this period look like war zones.
During the 1977 World Series, the cameras turned from Yankee Stadium to show a fire burning nearby. The commentator Howard Cosell looked out at the flames and said the words that defined an era. “Ladies and gentlemen, the Bronx is burning.”
The words were true. But they didn’t tell the whole story. Even as buildings burned, communities held together. Churches stayed open. Neighbours watched each other’s children. The bodegas kept their doors open through the worst of it.
The South Bronx had survived the Famine. It had survived the journey from San Juan. It would survive this too.
You can understand this resilience better when you read the full story of how the Bronx came back.
The Bronx Comes Back
Recovery began in the 1980s. Community organisations rebuilt housing block by block. The city invested in the South Bronx for the first time in decades. Families who had never left began to see their neighbourhood change.
Mott Haven today is one of New York’s most watched neighbourhoods. Artists moved in. Galleries opened. The Bronx Museum of the Arts expanded its programme.
Hunts Point Riverside Park restored access to the waterfront. For the first time in generations, residents could walk to the edge of the East River. They could sit by the water that their grandparents and great-grandparents had crossed to get to the Bronx.
The Longwood Art Gallery at Hostos Community College now showcases Latin American and Caribbean artists. Hostos itself — named after Puerto Rican intellectual Eugenio María de Hostos — has become one of the most important community colleges in New York.
The South Bronx also gave the world hip-hop. The art form was born in these streets in the 1970s, at the height of the fires. It was the community’s answer to destruction. It turned grief into music. Survival into culture.
Where to Visit Today: Tracing Heritage in the South Bronx
Start at the Bronx Museum of the Arts on Grand Concourse. The permanent collection focuses on art from Africa, Asia, and Latin America. Entry is free on Fridays.
Walk south to Mott Haven. The neighbourhood’s 19th-century row houses still stand along Alexander Avenue. This is the heart of the original Irish South Bronx.
St. Ann’s Church on St. Ann’s Avenue is the oldest church in the Bronx. It was founded in 1841. Irish families worshipped here for generations. The churchyard contains some of the oldest gravestones in the borough.
Hostos Community College on Grand Concourse is a monument to Puerto Rican academic ambition. Walk the campus and visit the Longwood Art Gallery.
Hunts Point Riverside Park reopened in 2011. It restored 8 acres of waterfront to public use. The views across the East River are extraordinary. This is where the South Bronx meets the water.
The Point CDC on Garrison Avenue in Hunts Point is a community development organisation. It has been rebuilding the neighbourhood since 1994. Its arts and community programmes are open to visitors.
If you’re tracing Irish heritage, the Ellis Island records are your starting point. Many South Bronx Irish families arrived through Ellis Island between 1880 and 1920. The names are searchable online.
For Puerto Rican genealogy, the Archivo General de Puerto Rico in San Juan holds civil and church records dating back centuries. The Center for Puerto Rican Studies at Hunter College in Manhattan also has an extensive archive.
Frequently Asked Questions
When did Puerto Ricans begin settling in the South Bronx?
Large-scale Puerto Rican migration to the South Bronx began in the late 1940s and accelerated through the 1950s and 1960s. By 1970, the South Bronx had one of the largest Puerto Rican communities in the United States outside of Puerto Rico itself.
What happened to the Irish community in the South Bronx?
The Irish community that built the South Bronx in the 19th and early 20th centuries largely moved to the suburbs of Westchester and Long Island in the post-war years. Their institutions — churches, schools, and community halls — often remained and were taken over by incoming Puerto Rican and Latino communities.
Is the South Bronx safe to visit today?
Yes. Mott Haven, Longwood, and Hunts Point have seen significant investment and community development since the 1980s. Heritage sites, museums, and community organisations welcome visitors. Like any New York neighbourhood, it is most enjoyable when explored with some local knowledge.
What is the best way to explore South Bronx heritage on foot?
A self-guided walk along Alexander Avenue in Mott Haven takes visitors past the neighbourhood’s oldest surviving Irish and later Latino architecture. Start at St. Jerome’s Church and walk north toward the Bronx Museum of the Arts. Allow two to three hours and stop for coffee at one of the local cafés along the way.
A Neighbourhood That Never Stopped Being New York
The South Bronx is not a story of decline. It is a story of arrival. Of people who had nothing, and built something from it.
The Irish came with empty pockets and full hearts. They built their churches and their political clubs. They paved the streets and ran the firehouses.
The Puerto Ricans came next. They took what was left and made it theirs. They added music and food and colour and warmth.
Both communities faced hardship here. Both were looked down on. Both refused to disappear.
When you walk Alexander Avenue today, you are walking on their work. When you hear salsa music from an open window, you are hearing the sound of everything that survived.
