You’ve likely seen the spooky photos of that crumbling stone tower in the middle of the East River. It’s the Octagon. Today, it’s a high-end apartment complex on Roosevelt Island where people pay thousands in rent. But back in the 19th century? It was the gateway to a literal living nightmare known as the Blackwell's Island mental asylum.
Honestly, the history is way darker than the "haunted house" stories you see on TikTok.
When the New York City Lunatic Asylum opened on June 10, 1839, the city actually had good intentions. Crazy, right? They wanted to get the "insane" out of Bellevue’s cramped basement and into a place with fresh air and sunlight. They thought the "Moral Treatment" model—basically just being nice and giving people hobbies—would cure mental illness.
It didn't. Not even close.
On day one, 197 patients were dumped there. The building was only designed for 200. By the time the ink was dry on the ledgers, the place was already at capacity. It only went downhill from there.
The Human Rat-Trap
That's what Nellie Bly called it. You probably know her name. In 1887, she faked insanity to get inside and write her famous exposé, Ten Days in a Mad-House.
She wasn't exaggerating.
The conditions were basically a checklist of "how to break a human being." Patients were woken up at 6:00 AM and forced to sit on hard, straight-backed wooden benches until bedtime. No talking. No moving. If you tried to stretch your legs, a nurse might box your ears or kick you.
One of the most horrific things Bly described was the "bath."
Imagine being stripped naked in a freezing room. Then, nurses throw buckets of ice-cold water over you. Or worse, they dunk you into a communal tub that hasn't been drained after twenty other women used it. The water was thick with "scum," but you were scrubbed with a brush until your skin was raw.
Food was another horror story.
- Black bread that was literally just dried, unbaked dough.
- Spilled "soup" that was mostly water and floating bits of meat.
- Oatmeal so wretched even the starving couldn't stomach it.
- No knives or forks—you tore meat apart with your bare hands.
While the patients starved, they could see the doctors and nurses through the kitchen windows eating fresh grapes, melons, and white bread. Talk about a "hierarchy of suffering."
Why Blackwell's Island Mental Asylum Was a Dumping Ground
Here is the part most people miss: many people in the asylum weren't even "insane."
In the 1800s, being poor, an immigrant, or an "unruly" woman was often enough to get you committed. Historians like Robert Mohl have pointed out that the island was essentially a way for elite New Yorkers to hide "undesirables."
The city used a "homogenization" strategy. If you didn't act like a "virtuous" upper-class lady, you were labeled morally corrupt.
Got caught in a "haunt of theft"? Asylum.
Language barrier because you only speak German? Asylum.
Lost your husband and have no money? Asylum.
Stacy Horn, in her book Damnation Island, notes that by 1868, the "Lodge"—a building for "violent" cases—housed 190 women. Its actual capacity was 66. The "Retreat" was built for the "noisy" cases, but even that became a warehouse for anyone the city didn't want to deal with.
The Turning Point
Bly’s reporting changed everything. After her articles hit the New York World, a Grand Jury visited. They didn't just look at the fancy Octagon entrance; they looked at the wards.
The result? The city dropped an extra $1 million (a fortune back then) into the budget. They fired the abusive nurses. They replaced the convict labor—yes, they were actually using prisoners from the nearby penitentiary to "guard" the mentally ill—with trained staff.
Eventually, the asylum was moved to Ward's Island in 1894. The old buildings were repurposed, renamed, and finally left to rot.

Blackwell's Island became Welfare Island in 1921. Then, in 1973, it became Roosevelt Island.
What You Can Do Now
If you’re a history buff or just someone who cares about how we treat people on the fringes, you can actually visit what’s left.
- See the Octagon: The central spiral staircase of the original asylum still stands. It’s been restored and serves as the lobby for the apartments at 888 Main Street. It is stunning and eerie at the same time.
- Visit the Blackwell House: It’s one of the oldest farmhouses in NYC and gives you a sense of what the island was like before it became an "island of lost souls."
- Read the Source Material: Don't just take my word for it. Read Nellie Bly’s Ten Days in a Mad-House. It’s in the public domain and is still a gut-punch of a read today.
- Check out the NYC Municipal Archives: If you're really into the weeds, they have the "Almshouse Ledger Collection." You can see the actual handwritten names of the people who lived and died there.
The ruins of the Smallpox Hospital (the Renwick Ruin) are also nearby. It’s the only landmarked ruin in the U.S. and serves as a permanent reminder of how the city used to "quarantine" its problems.
The legacy of the Blackwell's Island mental asylum isn't just about ghosts or old buildings. It's a reminder of what happens when we prioritize "out of sight, out of mind" over actual human care.
