New York City

Imagine a city where a secret train station sleeps beneath the streets, glittering with chandeliers that almost nobody ever sees. A city where you can whisper into a corner of a train terminal and a friend fifty feet away will hear you perfectly. A city where a famous hawk built his nest on a fancy apartment building and crowds gathered every day just to watch him. A city with more gold buried under one street than almost anywhere else on Earth.

That city is New York, and this book is full of its secrets.

More than eight million people live there — more than in the entire country of Switzerland — squeezed onto islands and shorelines where the Hudson River meets the Atlantic Ocean. They speak around 800 different languages, ride trains that never stop running, and walk past wonders most of them never notice.

How did a muddy little trading post become the most famous skyline in the world? Why do the skyscrapers cluster in some spots and not others? Who really built the Brooklyn Bridge? And what does a birthday party in the Bronx have to do with music you hear today?

Turn the page. The secrets are waiting.

Long before there were taxis or towers, the island at the heart of New York belonged to the Lenape people. They called it Mannahatta, which many scholars translate as "island of many hills." And it truly was hilly — covered in forests, streams, ponds, and meadows, with black bears in the woods and so many fish in the rivers that people said you could almost scoop them out with your hands.

The Lenape hunted, fished, planted corn and beans, and traveled the island on footpaths worn smooth by generations of walking. One of those paths ran the whole length of the island, winding cleverly around hills and swamps. It was called the Wickquasgeck Trail.

Here is the secret: that trail never disappeared. When Europeans arrived, they kept using the same path, then widened it into a road. Today it is called Broadway — the most famous street in New York. While almost every other street follows a neat modern grid, Broadway still wanders diagonally across the island, tracing a route the Lenape walked centuries ago.

So every actor, tourist, and hot-dog seller on Broadway today is following ancient footsteps. The oldest thing in New York City is hiding in plain sight: it is a walk.

In the early 1600s, ships from the Netherlands sailed into the great harbor. The Dutch were not looking for gold or glory. They wanted something fluffier: beaver fur. Beaver hats were the height of fashion in Europe, and the rivers around Mannahatta were full of beavers.

So in the 1620s the Dutch built a small settlement at the southern tip of the island and named it New Amsterdam. It looked nothing like today's New York. It had windmills, wooden houses with stepped roofs, a canal running down the middle of a street, and pigs and goats wandering the muddy lanes. Perhaps a few hundred people lived there — but even then, they came from all over the world and spoke many languages. New York has been a mixing pot from its very first days.

In 1653, the settlers built a tall wooden wall across the island to protect their town. The wall is long gone, but the dirt path that ran beside it became a street, and the street kept the name: Wall Street. Today it is home to the mightiest stock exchange on Earth.

A fence made of logs gave its name to the world's most famous money street. Not bad for a beaver-trading village.

In 1664, English ships sailed into the harbor, and New Amsterdam changed hands without a single cannonball being fired at the town. The English renamed it New York, after the Duke of York. The Dutch settlers mostly stayed, kept baking their crullers and cookies — in fact, the English word "cookie" comes from the Dutch word koekje, meaning little cake — and the city kept growing.

And growing. By the early 1800s, New York was bursting at its seams, so in 1811 city planners made one of the boldest decisions in city history. They unrolled a map of the still-wild island and drew a giant grid over it: twelve avenues running up and down, and more than 150 streets running across, like a sheet of graph paper stamped onto forests and farms. Hills would be flattened, streams buried, and the whole island organized into neat rectangles.

That grid is why it is so hard to get lost in Manhattan today. If you are on 34th Street and need to reach 42nd Street, just count eight blocks.

In 1898, New York joined together with Brooklyn, Queens, the Bronx, and Staten Island to form one enormous city of five boroughs. The little trading post now had room to reach for the sky.

Look at photographs of Manhattan and you will notice something curious. The skyscrapers bunch together in two big clusters — one at the bottom of the island and one in the middle — with lower buildings in between. Why?

Part of the answer lies deep underground. Manhattan sits on an incredibly hard, sparkly rock called Manhattan schist, formed under crushing heat and pressure around 450 million years ago — long before the dinosaurs. It glitters because it is full of a shiny mineral called mica. You can see it poking out of the ground in Central Park, like the bones of the island showing through its skin.

A skyscraper is astonishingly heavy. The Empire State Building weighs about 365,000 tons — roughly as much as a thousand fully loaded jumbo jets. A building that heavy needs to stand on something that will never squish or slide, and Manhattan schist is perfect. In the two places where the hard rock comes close to the surface, giants could rise.

So when you gaze up at that famous skyline, remember: it is also a map of what lies below. New York's towers grow where the island's ancient, glittering bedrock is strong enough to hold them.

Hard rock alone does not make a skyscraper. There was another problem: stairs. Nobody wants to climb forty flights of stairs to get home, so for most of history, buildings stayed short. Elevators existed, but people were terrified of them. If the rope snapped, the elevator would plunge. Who would ride a box hanging by a thread?

Then came Elisha Otis, a mechanic with a flair for drama. In 1854, at a big exhibition in New York's Crystal Palace, Otis stood on an open elevator platform and had it hoisted high above the crowd. Then, as everyone watched, his assistant swung an axe and cut the rope.

The crowd gasped. The platform dropped — an inch or two — and stopped. Otis had invented a safety brake with springs and metal teeth that grabbed the rails the instant the rope let go. He swept off his hat and called out, "All safe, gentlemen, all safe!"

Three years later, the first safety passenger elevator for the public was installed in a New York store on Broadway. Suddenly the top floor was not a punishment — it was a prize with the best view.

One showman, one axe, one cut rope: that is the secret ingredient of every skyline on Earth.

In 1930, New York was gripped by skyscraper fever. Builders competed to raise the tallest building in the world, and the boldest project of all began on Fifth Avenue: the Empire State Building.

What happened next still amazes engineers. The tower — 102 stories of steel, stone, and glass — was built in just 410 days. That is about thirteen and a half months to raise what was then the tallest building humans had ever made. At top speed, the frame grew four and a half floors in a single week.

The secret was teamwork run like clockwork. As many as 3,400 workers swarmed the site each day. Steel beams arrived from the factory still warm, hoisted into place within days of being made. A tiny railway with little cars ran along the floors, delivering bricks and materials right where they were needed. High above the city, workers called sky boys strolled along narrow beams, catching red-hot rivets in metal cans and hammering them home.

When it opened in 1931, the building stood 1,454 feet tall to the tip, with about 10 million bricks and 6,500 windows. From the top on a clear day, you can see five states. And it all went up faster than a school year.

The Empire State Building holds secrets most visitors never learn. Start at the very top: that elegant spire was not originally designed as decoration. Its builders planned it as a docking mast for airships — giant balloons like flying ocean liners — imagining passengers would step off onto a platform a quarter mile in the sky. The winds up there proved far too wild, and the idea was abandoned. But the dream gave the building its beautiful pointed crown.

The spire found a better job: broadcasting. In 1931, engineers began beaming experimental television signals from the tower — years before most people had ever seen a TV. New York was one of television's cradles: in 1939, regular American broadcasting began when cameras at the World's Fair in Queens showed President Franklin Roosevelt, the first U.S. president ever to appear on television.

More secrets: the building has its own zip code, 10118. Its lights change color for holidays — green for St. Patrick's Day, orange and black for Halloween. During bird migration seasons, the lights are dimmed on certain nights so travelers flying by starlight will not get confused.

And every year, runners race up its 1,576 stairs. The fastest climbers reach the 86th floor in about ten minutes. Phew!

In the 1860s, Brooklyn and New York were two separate cities, staring at each other across the East River. The only way across was by ferryboat, and when the river froze or fogged over, everything stopped. An engineer named John Roebling proposed something wild: a suspension bridge half again longer than any ever built, hanging from cables spun of steel — a brand-new idea at the time.

People said it was impossible. The East River was wide, deep, and busy with ships. To build the towers, workers had to dig the riverbed inside giant upside-down wooden boxes called caissons, sunk to the bottom and filled with pressurized air to keep the water out. Inside, by lamplight, crews nicknamed sandhogs dug through mud and boulders, sending the stone towers rising above them.

Those granite towers climbed 276 feet — for years among the tallest structures in New York, in an age when church steeples ruled the skyline. From them would hang four great cables, each containing thousands of miles of steel wire wrapped tight.

The bridge took fourteen years to build. And its greatest secret is not made of stone or steel at all. It is a person — someone the newspapers of the day barely mentioned. Her name was Emily.

The Brooklyn Bridge broke its builders one by one — and then a remarkable woman quietly took charge. John Roebling, the designer, was injured in a ferry accident before construction even began, and his son Washington took over as chief engineer. But Washington spent too long in the pressurized caissons and fell terribly ill with what workers called caisson disease. He became too weak to visit the site, watching through field glasses from his window in Brooklyn.

Enter Emily Warren Roebling, Washington's wife. She began carrying his instructions to the engineers — and then she did far more. Emily taught herself advanced mathematics, the strength of materials, and the art of cable construction. For more than a decade she met with engineers, answered questions from officials, and managed the greatest engineering project of the age. Many people on the site came to believe she was secretly the real chief engineer.

When the bridge opened in 1883, Emily rode across first in a carriage, carrying a live rooster as a sign of victory. A year later, showman P. T. Barnum led 21 elephants, including the famous Jumbo, across the span to prove to everyone how strong it was.

Today a plaque on the bridge honors Emily. The impossible bridge had a hidden hero.

In June 1885, a French ship called the Isère sailed into New York Harbor carrying the strangest cargo imaginable: a colossal woman, taken apart like a puzzle. The Statue of Liberty arrived in 350 pieces packed into 214 wooden crates — a giant folded up in boxes, with her face in one crate and her fingers in another.

She was a gift from the people of France, celebrating friendship and freedom, and she was the dream of sculptor Frédéric Auguste Bartholdi. Many say he modeled her calm, strong face on someone he loved dearly: his own mother.

Here is the part that surprises grown-ups. The statue looks like solid metal, but her copper skin is only about as thick as two pennies pressed together — around 2.4 millimeters. She is a hollow giant, like the world's largest piece of metal origami.

But there was a problem. The statue had crossed the ocean, yet her stone pedestal was not finished — the money had run out. A newspaper publisher named Joseph Pulitzer asked ordinary people to help, promising to print every donor's name. About 120,000 people sent in whatever they could, most giving less than a dollar. Schoolchildren mailed in pennies.

Kids' pocket money helped give Liberty a place to stand.

How does a hollow copper lady stand up to ocean winds for more than a century? The answer hides inside her. Beneath the thin copper skin is a strong iron skeleton designed by Gustave Eiffel — the very same engineer who later built the Eiffel Tower in Paris. His clever frame lets the skin flex gently instead of cracking. In strong winds, the statue actually sways a little, and her torch sways even more. She is built to dance with the weather, not fight it.

Here is another secret: she has not always been green. When the statue was unveiled in 1886, she was shiny reddish-brown, like a brand-new penny. Over the following decades, the sea air slowly turned her copper skin green — a natural coating called a patina. Far from being rust or damage, the patina actually protects the metal underneath, like armor the statue grew all by herself.

Everything about her carries meaning. The seven rays of her crown stand for the seven seas and seven continents. At her feet, often unnoticed, lies a broken chain — a symbol of freedom. From the ground to the tip of her torch she rises about 305 feet, and inside, a spiral staircase of 162 steps climbs up to the crown.

Here is a secret that fools almost everyone: Central Park looks like a lucky piece of leftover wilderness, but nearly all of it was designed and built by people, the way you might build a cathedral — except this cathedral is made of meadows, woods, and lakes.

In the 1850s, New Yorkers realized their booming city was running out of open space. The land set aside for a park was swampy, rocky, and rough. In 1858, a design contest was won by Frederick Law Olmsted and Calvert Vaux, whose Greensward Plan imagined rolling lawns, curving paths, and lakes where there was mostly muck and stone.

Then came the hard part. Around 20,000 workers, using shovels, horse carts, and blasting powder, reshaped 843 acres. They moved millions of cartloads of soil and rock, blasted stubborn bedrock with more gunpowder than was fired at the famous Battle of Gettysburg, and planted hundreds of thousands of trees and shrubs. Even the lakes are human-made: workers dug the hollows and filled them with water.

Olmsted and Vaux also hid the city's traffic in sunken roads so the park would feel like deep countryside. Their trick still works. Stand in the Ramble today and you can forget skyscrapers exist.

In 1991, birdwatchers in Central Park spotted something astonishing: a young red-tailed hawk with unusually pale feathers, hunting right in the middle of the city. Red-tailed hawks normally nest in tall trees or on cliffs far from crowds. This bird had other ideas. They named him Pale Male.

Pale Male chose the fanciest address imaginable. He built his nest on a ledge of 927 Fifth Avenue, an elegant apartment building across the street from the park, above windows belonging to movie stars. To a hawk, the decorated stone ledge probably looked like a perfect cliff — with a park full of food conveniently across the road.

He became one of the most famous birds in the world. Every day, fans gathered by the model boat pond with telescopes and cameras, watching him soar between skyscrapers, raise chicks, and teach them to fly over taxicabs. Books were written about him, and filmmakers made documentaries. Tourists who came to see paintings in nearby museums ended up watching a hawk instead.

Pale Male lived for more than three decades — a remarkably long life for a wild hawk — and helped New Yorkers see their city differently. Today, red-tailed hawks nest all over New York. The wild never left; it just adapted.

On October 27, 1904, New York threw a party underground: the subway opened, and about 100,000 people paid a nickel to ride beneath the streets for the very first time. The mayor himself drove the first train, and he enjoyed it so much he did not want to hand over the controls.

Today the subway is a world of its own: 472 stations — more than any other subway system on Earth — with hundreds of miles of track. Line them all up and they would stretch from New York past Chicago. It runs all day and all night, every day of the year.

But its loveliest secret lies hidden beneath City Hall. The system's original showpiece station was built like an underground palace: graceful arches of green and cream tile, skylights of colored glass letting in sunbeams, and brass chandeliers. It closed in 1945 because newer, longer trains could not fit its tightly curved platform, and most New Yorkers forgot it existed.

But the ghost station is still there, still beautiful. And here is the trick some riders know: stay aboard the number 6 train after its last stop, and as it loops around to head back uptown, it glides slowly through the sleeping station. Press your face to the window.

Grand Central Terminal, opened in 1913, is the world's largest train station by number of platforms — and it is stuffed with secrets.

Start with the ceiling of the main hall, painted like a glowing green-blue sky with golden zodiac constellations and 2,500 stars. Look closely and you will find something odd: the constellations are painted backwards! Some say the design was copied from a diagram showing the sky as seen from outside the stars — a heavenly view looking down, rather than our view looking up. Near the crab constellation, spot a small dark rectangle. When the ceiling was cleaned in the 1990s, workers left one patch untouched to show how grimy decades of smoke had made it.

Now for the best trick in the building. Head downstairs to the wide arched space outside the Oyster Bar restaurant. Have a friend stand in one corner, facing the wall, while you stand in the corner diagonally opposite. Whisper into your corner — and your friend will hear your voice clearly, as if you were beside them. The smooth tiled arches carry the sound up, over, and down. It is called the Whispering Gallery.

The brass clock atop the information booth has four faces made of precious opal glass. Experts value it in the millions.

Broadway earned a shining nickname more than a century ago: the Great White Way. It was one of the first streets in America to blaze with electric lights, and theater owners quickly discovered that glowing signs could stop crowds in their tracks.

The heart of it all is Times Square, which got its name in 1904 when the New York Times newspaper moved into a tower there. That New Year's Eve, the newspaper celebrated with fireworks — and a few years later, in 1907, it began a stranger tradition: lowering a glowing ball down a flagpole at midnight. The ball drop still happens every New Year's Eve. Today's ball weighs almost 12,000 pounds — about as much as an elephant — and sparkles with 2,688 crystal triangles.

Here is a secret adults rarely know: in Times Square, dazzling signs are not just allowed, they are required. City rules say buildings there must display huge, bright, glowing displays. It is likely the only neighborhood on Earth where the law commands the lights to shine.

All that glow celebrates Broadway's theaters, where shows run night after night, some for decades. The longest-running Broadway show, The Phantom of the Opera, played for 35 years — nearly 14,000 performances of the very same story.

Some of the world's favorite playthings were born in New York.

In 1902, President Theodore Roosevelt — who was born in Manhattan — went on a hunting trip. His companions cornered a bear and invited him to shoot it, but Roosevelt refused, saying it would not be sporting. A newspaper cartoon of the president sparing the bear charmed the whole country. In Brooklyn, a candy-shop owner named Morris Michtom saw the cartoon and had an idea. He and his wife, Rose, sewed a soft toy bear, placed it in the shop window, and called it Teddy's Bear — after writing to the president for permission to use his name. The bears sold so fast that the Michtoms started a toy company. That is how the teddy bear got its name.

Thirty years later, in the Queens neighborhood of Jackson Heights, an out-of-work architect named Alfred Mosher Butts set out to invent the perfect word game. To decide how many of each letter to include, he carefully counted letters on the front page of the New York Times. His game eventually became Scrabble, now found in millions of homes.

In Jackson Heights today, a street sign spells the neighborhood's name with tiny numbers under each letter — Scrabble scores, honoring the hometown inventor.

On a sticky summer day in 1902, a Brooklyn printing company had a problem. The humid air kept swelling and shrinking its paper, so colorful magazine pages came out smeared and misaligned. The company asked a 25-year-old engineer named Willis Carrier for help.

Carrier designed a machine that blew air across chilled pipes, pulling moisture out of the air and cooling it at the same time. He was only trying to rescue the printing — but he had just invented modern air conditioning. Within a few decades, movie theaters advertised their icy air, and eventually homes, schools, hospitals, and computers everywhere depended on Carrier's idea. Deserts bloomed with cities because a Brooklyn print shop had wrinkly paper.

New York gave the world tasty inventions too. In 1912, bakers at the enormous Nabisco factory in Manhattan's Chelsea neighborhood created a new sandwich cookie: two chocolate wafers hugging a creamy filling. They called it the Oreo. That old factory is now Chelsea Market, a famous food hall, and the street beside it carries the honorary name Oreo Way.

And from Brooklyn came the mysterious egg cream — a beloved fizzy drink of milk, seltzer, and chocolate syrup that contains, famously, no egg and no cream. New Yorkers love that joke to this day.

On August 11, 1973, a teenager in the Bronx named Cindy Campbell wanted to earn money for back-to-school clothes. So she organized a party in the recreation room of her apartment building at 1520 Sedgwick Avenue, charging 25 cents for girls and 50 cents for boys. For the music, she asked her 18-year-old brother Clive — known as DJ Kool Herc — to bring his powerful sound system.

That night, Herc tried something new. He had noticed that dancers went wild during the break — the part of a song where the singing drops out and the drums take over. So he set up two turntables with two copies of the same record and switched between them, playing the break again and again, stretching a few seconds of drums into minutes of nonstop beat. He called it the merry-go-round.

The dancers, soon called break-dancers or b-boys and b-girls, invented spinning, popping moves to match. Friends spoke rhythmic rhymes over the beats. Artists painted dazzling letters on walls, and a whole culture bloomed: DJing, rapping, breaking, and graffiti art — hip-hop.

From one rec-room birthday party, hip-hop grew into one of the most popular kinds of music on the planet. It all started with a sister, a brother, and fifty cents at the door.

Remember the wooden wall the Dutch built in 1653? The street beside it, Wall Street, went on to have the strangest career of any street on Earth.

In 1792, twenty-four merchants gathered under a buttonwood tree there and signed an agreement to trade stocks — little pieces of companies — with one another. That handshake under a tree grew into the New York Stock Exchange, where today trillions of dollars' worth of shares change hands.

In 1867, a New Yorker named Edward Calahan invented the stock ticker, a machine that printed prices on long ribbons of paper tape. Offices filled with curling tape — and New Yorkers found a joyful use for it. During big parades, workers flung clouds of ticker tape out of windows, letting it flutter down like snow. The first great ticker-tape parade happened in 1886, celebrating the Statue of Liberty. Astronauts, ball teams, and heroes have been showered ever since.

The biggest secret sits nearby, at the Federal Reserve Bank of New York. Eighty feet below the street, resting on bedrock, is a vault holding hundreds of thousands of gold bars — one of the largest piles of gold on Earth, much of it kept safe for other countries. Golden treasure, sleeping under the sidewalk.

New York has always been a launching pad for big ideas.

In 1858, Rowland Hussey Macy opened a small dry-goods store that grew into Macy's, one of the largest department stores in the world. Its logo is a red star — matching a star tattoo Macy got as a young sailor on a whaling ship. In 1924, Macy's employees, many of them immigrants missing the festivals of home, held a parade that became the Macy's Thanksgiving Day Parade. Giant character balloons joined in 1927, starting with Felix the Cat. In the early years, the balloons were released into the sky at the end of the parade, wearing return-address labels — anyone who found one and mailed it back earned a reward!

The list of New York firsts goes on. Tiffany's dazzling jewelry store began there in 1837. Pfizer, which makes medicines used worldwide, started in a Brooklyn building in 1849. And in 1969, a New York bank called Chemical Bank opened something brand-new just outside the city: the first automated teller machine in America. Its advertisement made a bold promise: on September 2, our bank will open at 9:00 and never close again. Money from a machine in the wall seemed like magic. Now ATMs stand on corners all over the world.

Ride the number 7 train through Queens and you take a trip around the world without a passport. In one stretch of neighborhoods you can hear Spanish, Bengali, Korean, Mandarin, Greek, Nepali, Tibetan, and dozens more. Scientists who study languages believe New York City is home to around 800 languages, making it possibly the most linguistically diverse city in human history. Some languages endangered in their homelands survive in New York kitchens and playgrounds.

All those cultures brought their recipes. Bagels arrived with Jewish bakers from Eastern Europe. In 1905, Lombardi's in Manhattan became the first pizzeria in America, and New Yorkers have argued about the best slice ever since — many insist the secret ingredient is the city's famously good tap water in the dough. Hot dogs found their fame at Coney Island in Brooklyn, where a boardwalk stand called Nathan's grew world-famous.

When you want to see it all, do what smart travelers do: ride the Staten Island Ferry. It sails right past the Statue of Liberty with knockout views of the skyline, runs all day and all night — and costs absolutely nothing.

And guarding the Public Library on Fifth Avenue sit two marble lions with perfect New York names: Patience and Fortitude.

Here is a secret even many New Yorkers are only beginning to learn: their city is going wild again, in the best way.

Long ago, New York Harbor was the oyster capital of the world. Its waters held hundreds of square miles of oyster reefs — by some estimates, a large share of all the oysters on Earth. Oysters are heroes: a single one can filter up to fifty gallons of water a day, and reefs make homes for fish and soften big waves. Over the centuries the reefs faded away. So today, students in the Billion Oyster Project are growing baby oysters in classrooms and planting them in the harbor by the millions — more than one hundred million so far — with a goal of one billion.

The cleaner water is bringing astonishing visitors. Humpback whales now surface in sight of the skyline, gulping fish with skyscrapers behind them. Seals lounge on harbor islands in winter.

Even the sun puts on a show. Twice a year, on evenings around late May and mid-July, the setting sun lines up exactly with Manhattan's street grid and blazes down every cross street at once. A scientist from the Bronx, Neil deGrasse Tyson, gave the spectacle its perfect name: Manhattanhenge.

So now you know the secrets. You know that Broadway follows a footpath older than the city itself, and that Wall Street is named for an actual wall. You know a showman cut an elevator rope to give us skyscrapers, and that the tallest one of its day rose in 410 days. You know Emily Roebling quietly finished a bridge the world called impossible, and that Lady Liberty crossed the ocean in 350 pieces, paid for partly with children's pennies.

You know where the ghost station sleeps, where the whispering corners are, which ceiling has backwards stars, and why the harbor is filling with baby oysters. You know that a birthday party can change music forever, and that a candy-shop owner, an unemployed architect, and a young engineer can change bedtime, game night, and summer itself.

Notice what all these stories have in common? None of them started with someone famous or powerful. They started with someone curious — someone who looked at a problem and thought, what if?

New York was built by dreamers who came from everywhere, carrying ideas in their pockets. The city is not finished; it never is. Somewhere out there is a secret waiting for you to find it — or better yet, to build it. What will yours be?
