Since its completion in 1902, the Flatiron Building has stood as one of New York City's most photographed, most mythologized, and most instantly recognizable structures. But beneath the iconic silhouette lies a wealth of stories most New Yorkers — and most tourists — have never heard.
It Wasn't Originally Called the Flatiron
When it opened, the building was officially named the Fuller Building, after its developer and builder, George A. Fuller. The name "Flatiron" was already in common use before the building even rose — the triangular plot of land at the junction of Fifth Avenue, Broadway, and 23rd Street had long been nicknamed "Eno's Flatiron," after its former owner Amos Eno. The popular nickname proved irresistible, and "Fuller" never stood a chance.
Construction Took Just One Year
Thanks to a revolutionary steel-skeleton construction method — one of the first buildings in New York to use it — the Flatiron rose at the extraordinary pace of roughly one floor per week. Construction began in 1901, and the skeletal frame was complete by February 1902. The entire project was done in under a year.
People Genuinely Feared It Would Collapse
At 285 feet tall on an impossibly thin triangular footprint, the building was widely expected to topple in the wind. The New York Times predicted it would stand no more than 12 stories — it ended up being 22. Crowds reportedly gathered nearby to watch the expected disaster. The steel frame held fast, and the building has stood for over 120 years.

The building's wedge shape created powerful downdrafts along 23rd Street. Women's skirts would fly up scandalously, drawing crowds of men hoping for a glimpse of ankle. This spawned the slang phrase "23 Skidoo" — what police used to shoo away loitering onlookers. The 23rd Street subway station still has tiled mosaics of windblown hats in tribute.
It Was the Tallest Building North of Wall Street
When completed, the Flatiron was the tallest building in New York City north of the Financial District, and the first true skyscraper north of 14th Street. The Chrysler Building and Empire State Building would eventually surpass it in height, but nothing would match its instantly memorable form.
The Facade Is Not Actually Triangular
The building sits on a right-angled triangle, not equilateral as many assume. Its sharpest point tapers to just six feet wide at the narrowest northern tip — the extreme slenderness that makes it appear so impossibly thin from certain angles.
It Had No Women's Bathrooms at First
Planners assumed an all-male tenancy and the building opened with no restrooms for women at all. The fix was unusual: odd-numbered floors became women's bathrooms and even-numbered floors became men's.
The Original Elevators Were Powered by Water
The Flatiron's hydraulic elevator system took a full ten minutes to reach the top floor and caused frequent flooding. A publishing executive reportedly threatened to rappel down the building's exterior in front of reporters rather than ride the elevator again.
It Inspired Countless Artists and Photographers
Edward Steichen and Alfred Stieglitz both created iconic photographs of the building in its early years. It became a subject of fascination for the Ashcan School of painters and continues to attract photographers from around the world more than a century later.
"It appeared to be moving toward you like the bow of a monster ocean steamer — a picture of new America still in the making."

Macmillan first moved a division in during 1969, and by the early 2000s its parent company Holtzbrinck Publishing Group occupied virtually every floor. The Flatiron imprint of Macmillan Publishers, which still exists today, takes its name directly from the building.
A Giant Ad Banner Once Covered the Entire Facade
During a 2005 renovation, a 15-story-tall vertical advertising banner was draped across the building's famous facade. Public protests erupted and the banner was removed early — a rare case of popular sentiment winning out over a commercial contract.
It Sold at Auction in Dramatic Fashion
In March 2023 the building sold for $190 million to a bidder who then couldn't produce the 10% deposit. It went back to auction in May 2023, and Jeff Gural's GFP Real Estate secured it for $161 million — this time with a $100,000 certified check required at the door.
It Is Now Becoming Luxury Residences
After 120+ years as office space, the Flatiron is being converted into 38 luxury condominiums designed by Studio Sofield, priced from $10.9 million to $50 million. Over 1,000 windows were replaced and thousands of terra-cotta pieces meticulously restored.
The Basement Extends Beyond the Building's Lot
The Flatiron's basement vaults extend roughly 26 feet west, 22 feet east, and 50 feet north — burrowing beneath adjacent sidewalks and roadways. This subterranean expansion totals nearly 8,600 square feet and was essential given the site's extreme triangular constraints.
Its Triple Landmark Status Is Virtually Unique
The Flatiron holds three landmark designations: NYC Landmark (1966), National Register of Historic Places (1979), and National Historic Landmark (1989). This triple protection ensures the building's iconic exterior will endure no matter what happens inside.
