Americans May Not Be Aware Of The Mysterious Things Hiding Within These Iconic U.S. Landmarks

The Statue of Liberty, Brooklyn Bridge, Mount Rushmore — you’ll probably recognize them all. From history class to travel brochures, these iconic locations are everywhere. Even if you’re lucky enough to have caught a glimpse of one in real life, it’s unlikely you would have been let in on the secrets concealed inside. Hiding just below the surface, there’s much more to these sites than first meets the eye. It’s time to expose the secret spaces, hidden places, and little-known quirks that lurk within some of America’s most legendary landmarks. So, next time you lay eyes on these famous spots, remember to take a second look.

1. New York public libraries’ secret apartments

Burrowed behind the bookshelves of many public libraries in the Big Apple are a series of abandoned apartments that once housed the library wardens. You see, in a time before central heating, these institutions needed around-the-clock assistance to keep the coals burning, books warming, and the decaying force of damp away.

Ghosts of the past

Today, these neglected quarters still sit out of sight behind the libraries’ walls. Peeling panels and rotting plaster that clings onto old rotary telephones paint a picture of what life was like in the apartments. And as of 2016, Atlas Obscura reported that 13 dwellings are still hidden among the shadows of the city’s libraries.

2. The Frick Collection’s buried bowling alley

Sitting in the cellar of one of NYC’s most celebrated art collections is a showpiece of the strangest kind. You see, buried floors beneath the Frick’s art-adorned walls, there is — unbeknown to most — a beautifully ornate bowling alley. Commissioned in 1914 by one of America’s most successful industrialists, Henry Clay Frick, the lavish recreation space was finally completed two years later. Just head down the stairs to the basement...

For your eyes only

Two-holed balls are spun down smooth pine alleys and retrieved using only the hand of gravity in a loop-the-loop contraption. The exquisitely decorated bowling alley was completed in 1916, but fire concerns saw it later close down. And despite being renovated 81 years later, the hall still sits largely forgotten and seductively frozen in time.

3. The Supreme Court Building's hidden hoops

Apparently, there’s a court that’s above even the highest one in the land. Yes, one story up from the Supreme Court’s fourth-floor library, there’s a place to let off steam and play some basketball. Off-duty cops, clerks, and attorneys have been lining up for games here ever since the storage space was first transformed in the 1940s. There’s just one important rule that must be followed.

The highest court in the land

The sign that hangs outside clearly states, “playing basketball and weight lifting are prohibited while the court is in session.” And while members of the public may not be able to play any ball at the concealed court, the venue has attracted some big shots throughout its history. The converted storeroom has hosted both Justices William H. Rehnquist and Byron White have been known to dunk baskets at the curious sports arena.

4. The New Yorker Hotel’s tucked away tunnel

While all camera lenses fall on The New Yorker’s sky-scraping scarlet sign, what lies below the famous Big Apple landmark remains largely forgotten. Sitting deep beneath the hotel is a subterranean passage that few people know about. Once upon a time, this tunnel transferred guests coming from Pennsylvania Station to the hotel lobby.

One final ride

The burrow was sealed up when the old Pennsylvania Station was bulldozed in 1963. But the tunnel remains even now. Before that final train ride, guests would be greeted by a porter and ushered through the passageway and all the way up into the hotel. Nowadays, the passageways are filled with piles of surplus hotel fittings and outdated furnishings. But among the gloom, beautiful mosaics of technicolor tiles still cling to the walls — little fragments of both a hotel’s history and long-forgotten Art Deco design. 

5. Roxy’s hidden home at Radio City Music Hall

Another Art Deco masterpiece with an undisclosed secret of its own is Radio City Music Hall. High up in the eaves of this elaborate theater lies a luxurious, gold leaf-lined living space that’s full of slick custom-crafted furniture. The keys were handed to the venue’s impresario Samuel “Roxy” Rothafel in 1932. And A-listers are still entertained up in the roof of Radio City Music Hall today.

The secret penthouse

Mick Jagger, Mariah Carey, and John Legend have been among those to pay a visit to Radio City Hall’s secret penthouse in recent years. It’s hard to believe that a venue as big as this can hide such a well-kept secret inside its very roof. But it’s true: while the stars themselves may be familiar, few regular folks know of the theater’s hidden attic apartment.

6. Step below The Lincoln Memorial

Even more surprising, perhaps, is the secret underground maze that sprawls beneath the Lincoln Memorial. Before they could get to work on the marble monument back in 1914, engineers first had to burrow 40 feet into the ground. They then installed a 43,800-square-foot cellar beneath the statue. But the hidden basement hoards far more than just structural pillars and concrete foundations.

An unexpected discovery

In 1975 workers began exploring the foundational cavity and found an eerie grotto where rodents scurried between stalactite-suspended columns. And carved into these stones were a series of mysterious sketches that were engraved by the original construction workers. According to Atlas Obscura, there are plans afoot to open the so-called undercroft to the public — allowing the memorial’s visitors to tour around this forgotten fossil of early 20th-century history.

7. Times Square’s Ghost Tower

At New York’s frenzied Times Square, many eyes are on the exterior of the soaring One Times Square skyscraper. According to the official Times Square website, an average of 360,000 pedestrians pass through each day. But what many tourists don’t know, however, is that despite being one of the world’s most popular sites, One Times Square is surprisingly empty inside.

One lone resident

Because the tower’s digital billboards are in such a prime location, its owners — Jamestown L.P. and Sherwood Equities — don’t need tenants to bring in the big bucks. So, the building lies empty beyond the third floor, while further up the tower there is apparently only one resident, Jeff Straus, who runs the New Year’s Eve festivities.

8. Hidden luxury at the Grand Central Terminal

While most people can be seen chasing down their commuter trains at the Grand Central Terminal, others there are busy sprinting after something else. Hidden high up on the top floors of the heaving terminal is a complex that includes “one regulation-sized indoor hardcourt, [a] junior court, two practice lanes, and a fully equipped fitness room.” Spot of tennis, anyone?

Members only

That’s according to Vanderbilt Tennis Club’s official website – the luxury sports club that is behind the station’s concealed tennis courts. The sport space is arguably the best-kept secret of one of America’s busiest terminals, with tennis lovers having batted many balls there since 1966. But despite the huge number of visitors the station attracts, few Americans actually know about these private courts.

9. The Waldorf Astoria’s “Track 61”

It seems that the New Yorker isn’t the only Big Apple hotel that’s hiding a subterranean secret. You see, lurking beneath the luxurious Waldorf Astoria New York is a tucked-away terminal known as “Track 61.” And according to the Daily Mail, it is still allegedly used today to sweep politicians and prolific celebs out of the city in secrecy.

VIP passengers

Joined to the hotel by a secret elevator, the station was apparently used during WWII to shuttle Franklin D. Roosevelt between his city suite and home in Hyde Park. Roosevelt and George W. Bush are the only verified VIP passengers, in fact. But the strangely unidentified door that still connects the Waldorf to the station is perhaps evidence that heads of state and big celebrity names still climb aboard the escape train today.

10. The Statue Of Liberty’s secret

Forget the crown; people used to ascend all the way up to the Statue of Liberty’s torch. Thanks to the entry room inside Lady Liberty’s light, until 1916 tourists could enjoy sweeping vistas across the city from inside the torch itself. And though the room still sits in the recesses of the statue, its closure to the public keeps it a mystery from the many visitors who ascend the huge monument nowadays.

A lady never tells

When the pier that once joined Jersey City to Black Tom Island was blown up by German agents during World War I, a storm of debris circulated the city and burrowed itself inside the statue’s light. This turned the former tourist pathway into a treacherous route, and so the torch’s inner access area has been shut ever since – making it arguably Lady Liberty’s best-kept secret.

11. A hidden hatch atop The Washington Monument

According to Atlas Obscura, 800,000 sightseers descend upon the Washington Monument each year. But few catch a glimpse of this little-known quirk. You may have wondered how staff go about repairing and caring for the world’s highest stone monument – a towering 555 feet tall, to be precise. Well, tucked away on the very tip of the structure is a secret trap door that allows workers to do just that.

The eastern side

This perfectly hidden hatch gives staff from the National Park Service scaffold-free entry onto the obelisk and stops repairs from ruining the tourist snaps. Cut into the monument just below its peak, the doorway allows workmen to hoop cables over its head and traverse down the monument to tend to breakages. Study the statue’s eastern face for a look at the discrete doorway. You may need your binoculars, though, for the white-washed hatch blends in perfectly with the monument’s marble.

12. The Washington Monument’s mysterious replica

But a camouflaged entrance isn’t the only quirk that the memorial conceals. Bizarrely, hiding in a manhole not far from the famous column is a 12-foot-high copy. Deposited in the 1880s, the doppelganger was boxed into a brick encasing and stashed underground. The real use for this bizarre mini-me is actually essential to the preservation of the iconic landmark, and far more scientific than you’d imagine when peering into the murky depths.

Sinking into the depths of the Earth

Drew Smith, a manager at the National Geodetic Survey, has explained the significance of the miniature Washington Monument to Atlas Obscura. Apparently, it is one of the many Geodetic Control Points that are used by surveyors as “starting points for any map or measurement.” In simple terms — it shows if the National Mall and its surrounds are starting to sink. Either way, it’s a little-known quirk just waiting to be explored.

13. Disney’s covert club

Behind all the magic and childhood wonder of its parks, Disneyland has a secret adult world that’s waiting to be explored by the elite. One ordinary door in New Orleans Square in California unlocks Club 33. This is an invite-only dining lounge and jazz club where the affluent can enjoy the only alcohol that is available in the park.

Fit for royalty

Yet while seeing the club’s intimate decor and the vintage artifacts straight out of Walt Disney’s study may be tempting, membership doesn’t come cheap. After a joining fee of up to $25,000, according to Insider, members have to pay between $12,000 and $30,000 per year if they wish to remain on the guest list. It’s certainly not for us average Cinderellas, though the club does happen to contain her glass slipper.

14. The Empire State Building’s forgotten floor

Fans of Taylor Swift might already know about this one, given that the singer promoted her track “Welcome To New York” while posing on the platform. But for everyone else, the observation balcony that stands on the 103rd story – just one level up from the floor viewing deck – is the Empire State Building’s untold secret.

An incredible view

Owing to the only knee-high barrier on the 103rd floor, elevators don’t actually carry members of the public there. So, if you do head up the tower for panoramas of the city, you’ll have to make do with whatever you can see over the high railings of the 86th story. Alternatively, you can enjoy views from behind the screens of the 102nd floor.

15. A hidden world under the Hoover Dam

Most flock to Lake Mead National Recreation Area for its jet skiing, kayaking and astounding views of the Hoover Dam. However, other visitors are more concerned with what’s going on underneath the water. Between scarlet scuba flags, thrill-seekers can dive down to the depths of Lake Mead and discover a sunken maze of tunnels and train lines that lie half-buried at the attraction.

Beneath the water

The decomposing remains of this ambitious construction project lie dormant under the water. Beneath the curvatures of crumbling tunnels, tracks that once transported building materials bisect the lake bed. This fantastically preserved underwater world is a well-kept secret of the diving community, who are able to see the famous landmark in an entirely different light.

16. Hidden in the walls of Pixar Studios

Sitting within the walls of the celebrated Pixar Studios is a secret hangout spot for its most renowned celebrity visitors. And, of course, there has to be a top-secret entrance for such an exclusive venue. Lucky guests will have to crouch, though, as the original access was via a minuscule hatch. Once inside, the so-called Lucky 7 Lounge’s impressive signature wall features doodles from songwriter Randy Newman, Buzz Lightyear actor Tim Allen, and Roy Disney.

Portal to another world

Steve Jobs also apparently liked to socialize in the secret lounge. And if a host of elite visitors didn’t make it exclusive enough, the way that the stealthy hideout was discovered makes the venue even more seductive. Apparently, Pixar animator Andrew Gordon unearthed the space after stumbling upon a portal big enough for a grown man to worm his way through at the tail end of his office.

17. The Grand Canyon’s hidden hotel

You may want to take a picture of the Grand Canyon, but have you ever considered sleeping inside it? Well, unlike the exclusive lounges and secret celebrity party spots that we’ve already explored, the Grand Canyon is one famous landmark with a hidden hideout that doesn’t require you to be an A-lister.

Catching some Zs

And while many know about the landmark’s popular tours and rafting excursions, few people realize that you can actually catch some Zs inside its infamous caves. Courtesy of Grand Canyon Cavern, guests can enjoy a fully-fledged hotel suite complete with lounge and bathroom – allowing you to hunker down in the burrows of America’s beloved canyon in comfort.

18. Mount Rushmore’s mysterious chamber

The granite-cut presidential portraits of Mount Rushmore are glanced upon by many, but few know about the secret vault that is carved out of the rock behind Abraham Lincoln’s head. After it dawned on the memorial’s sculptor Gutzon Borglum that his ambitious ode to America may be too complex, he committed only to the four portraits. And the artist left the remaining historical highlights for a chamber that would be chiseled into the granite beyond.

Hidden hall of fame

Though it is too dangerous for tourists to access, the secret stash still stands just behind the frontal lobe of Abraham Lincoln. Apparently, hidden within this forgotten hall of fame is a hoard of American charters – including duplicates of both the Bill of Rights and the Declaration of Independence. And these are all fittingly stored behind the Great Emancipator himself.

19. The Niagara Falls’ dark curse

And it turns out that Mount Rushmore isn’t the only celebrated landmark with a secret grotto. Carved into the cliff face of the Niagara Gorge is the mysterious “Cave of the Evil Spirit.” This legendary lair is supposedly named after the wicked spirits that were once locked within its dripping limestone walls.

Behind the falls

The legend behind this oft-overlooked cave begins in 1763 when a truckload of British troops was believed to have called in on the site. A Seneca tribe supposedly killed 80 of them in a surprise attack, and the soldiers’ spirits were said to have raided the den. Apparently, you can still hear their souls inside the hollowed hideout today. If you’re skittish, it may be best to stick to the majestic falls that otherwise drown out this dark history.

20. Buried cellars beneath Brooklyn Bridge

One of the more curious secret spaces explored in this list is the wine cellar complex that sits among the shadows under the Brooklyn Bridge. In order to redeem some of the city’s debts, the bridge was devised with a series of secret chambers set into the recesses of its foundations on both the Manhattan and Brooklyn riverbanks.

Cavernous remains

Once leased out to local traders, the hidden spaces were created to help with the $15 million incurred from building the bridge itself – and they did. Buried beneath 60,000-ton granite gateways, the round-the-clock chill of the concealed vaults seems to have attracted wine vendors everywhere. And while wine bottles no longer adorn the anchorage, the caverns still remain. They also contain an engraving that reads, “These cellars were built in 1876... From their inception, they housed the choicest wines in New York City.”
