10 Biggest Historical Mysteries In The World That Can Not Be Solved 10 Biggest Historical Mysteries In The World That Can Not Be Solved

From New York to San Francisco, these are the best spots in the United States that you can't visit.

It also contains numerous unique areas that can't be visited at all. It's probably for the best that most people never get to witness these hidden, off-limits places. Some of the most fascinating sites in the world are off-limits to the general public for various reasons. These include everything from secret military facilities and high-security prisons to hidden islands and underground clubs.

Read on for an introduction and compilation of data about obscure locations across the United States, brought to you by the folks at

National Security Agency Spy Hubs

In 2016, articles from all around the world started to discuss the rumored presence of covert espionage bases in America.

This one, the nearly windowless 33 Thomas Street (formerly the AT&T Long Lines Building) in Manhattan, is said to be just one of eight buildings, with the others located in Atlanta, Chicago, Dallas, Los Angeles, San Francisco, Seattle, and Washington, DC. The buildings are reportedly run by the National Security Agency.

Nobody truly understands what occurs inside.

1.Area 51, Groom Lake, Nevada

The tourists aren't allowed to visit Area 51

The United States Air Force calls Area 51 a "highly classified facility." However, this hasn't stopped some people from assuming the base is engaged in alien contact.

Civilians have never been allowed inside Area 51, despite a viral Facebook event in 2019 called "Storm Area 51, They Can't Stop All of Us."

Long a topic of speculation, the United States government finally acknowledged Area 51's existence in 2003.

The top-secret US Air Force facility has been at the center of several extra-terrestrial conspiracy theories, such as the moon landings having been staged and an alien lab being in operation. The facility gained notoriety during the Cold War when it was used to test aircraft. It is still in use and off-limits to the public, but those with an interest can learn more at the nearby Alien Research Center, a souvenir shop housed in a metal hangar.

2.Fort Knox, Kentucky

Fort Knox is home to the country's gold reserves

Has the phrase "like Fort Knox" ever been used to describe something? Because, you know, the real Fort Knox is pretty much indestructible.

The United States Army base in northern Kentucky spans three counties (Meade, Hardin, and Bullitt) and contains 4.2 million kilograms (147.3 million ounces) of gold bullion. That's around 50% of what the US Treasury has on hand.

The location is restricted to authorized personnel only and has strict security measures in place. It's like being in Fort Knox, in fact.

Although the rest of Fort Knox functions as a typical Army station, replete with a high school, the Bullion Depository has only been accessible to civilians twice: in 1974, when members of Congress and the media visited, and again in 2017.

3.Club 33, Anaheim, California

New Orleans Square is a recreation of the famous Louisiana city and can be seen in Disneyland Park in Anaheim. Club 33, an exclusive club, is rumored to be located in this area.

Walt Disney had planned to use the club to host high-profile events before his untimely death prevented that from happening. The exclusive club has added a waiting list and is rumored to charge its members upwards of £20,000 ($30,000).

Membership to Club 33 at Disneyland's New Orleans Square costs $40,000.

It was the only place in the park where alcoholic beverages could be purchased until fairly recently. You need to be invited by a member or get off the 14-year waiting list to gain access.

The number 33 may refer to "its location at 33 Royal Street" or the "thirty-three companies that provided the initial funding for Disneyland."

4.Tillamook Rock Lighthouse, Oregon

Tillamook Rock Lighthouse, located on a basalt stack in the Pacific Ocean, is affectionately known as "Terrible Tilly" due to its ominous appearance.

It was constructed in 1881, and tragically, the master mason who was assessing the site prior to construction was lost at sea. In January 1881, just before completion, a ship wrecked nearby, killing all 16 people on board. This storm occurred while laborers were isolated on the rock without supplies.

Tilly has been permanently closed since 1957 because of safety concerns, however she can still be seen from Tillamook Head's shore.

5.Ni'ihau Island, Hawaii

Hawaii’s so-called ‘Forbidden Island’, Ni’ihau

Over 170 people make their home on Ni'ihau, the 'Forbidden Island' of Hawaii, which is located about 15 miles (24 km) off the shore of Kaua'i.

For years, curious vacationers have been baffled by the invitation-only travel spot. When Elizabeth Sinclair bought the island from the last monarch of Hawaii, Kamehameha V, she made a commitment to keep it private and off-limits to everyone else.

Her great-grandsons, Keith and Bruce Robinson, now own it and have kept it off-limits to the public. Ni'ihau, with its stunning blue waters, appears to be as mysterious as it is beautiful.

6.Coca-Cola Vault, Atlanta, Georgia

What The Coca-Cola Corporation plans to do with the secret recipe for its signature soft drink. Seeing the exhibit at World of Coca-Cola in Atlanta, Georgia, which includes the Coca-Cola Vault, is the next best thing to actually tasting the secret formula. The recipe is locked away in a bank-style safe where only a select few have the combination.

The actual recipe is kept in "a metal box inside a 6.6-foot-high step vault, which is in turn protected by a barrier," and the whole "area has surveillance with armed guards, and the door can only be opened via keypad with hand scanner." You can get pretty close, though, thanks to the many interactive components at the world of Coca-Cola.

7.Langley, McLean, Virginia

Many people are familiar with Langley because it frequently appears in American political thrillers and crime dramas, and because of the mystery that surrounds this impenetrable complex.

This building is the CIA's headquarters; its official name is the George Bush Central Intelligence Agency (CIA). Of course, no one with anything less than top-secret clearance is allowed anywhere near Langley.

8.The Mormon Church, Salt Lake County, Utah

The Church of Jesus Christ of Latter-day Saints, also known as the Mormon Church, has a highly secure vault somewhere in the breathtaking natural settings of Utah's Salt Lake County. The largest collection of historical records can be found inside Granite Mountain Records Vault, which is 183 meters (600 feet) deep inside the rock of Little Cottonwood Canyon. Due to this, no public access is permitted, and few people are aware of the facility's location.

A vault hidden within a Utah rock formation houses approximately 35 billion images of genealogical data that belong to the Mormon Church. Although it is maintained by 50 workers on site, nobody else is permitted inside the vault.

In April 2010, a virtual tour became available. "It's a place for preservation. It would be challenging to maintain temperatures and keep it under control if we were constantly marching visitors through "Brent Thompson, who oversees the preservation operations for the Church History Department.

9.Googleplex, Mountain View, California

Google has locations in more than 150 countries, including several US data centers. Googleplex, the business's global headquarters in Mountain View, a suburb of San Jose, serves as the primary hub.

There are some restrictions, but curious visitors are welcome to explore the vibrant, sculpture-filled grounds. However, the building itself has much tighter security, with visitors only permitted if escorted by a staff member and no tours available (despite high demand).

10.Bohemian Grove, in San Francisco, California

Bohemian Grove is a private club for the most powerful men in the US

The most influential men in the US belong to a private club called Bohemian Grove. The group's members travel to the ranch every July for a two-week retreat to unwind and specifically not network.

Although little is known about the retreat, the group claims that its members "share a passion for the outdoors, music, and theater."

A Spy Magazine reporter infiltrated the club in 1989 and reported that there are other "bizarre rites" that occur every year in addition to some "Druid tree worship thrown in for fun." The wait had increased to 33 years by that year, so good luck trying to join.

It's unlikely that you'll ever find yourself in Bohemian Grove, California, unless you're one of the richest and/or most influential men in America.

The Bohemian Club, a private organization based in San Francisco that has counted numerous US presidents and celebrities among its members, including Ronald Reagan, George W. Bush, and Clint Eastwood, hosts a sort of summer camp at the restricted 2,700-acre campground. The male-only members of the secret society, which was established in 1872, gather in the campground visible in this aerial shot every year.

11.North Brother Island, New York City

North Brother Island in New York City

To put it mildly, North Brother Island has had a troubled past. Before Riverside Hospital (shown in the current picture), which was constructed for people with contagious diseases, was built, the island in the Bronx, on New York's East River, was uninhabited.

More than a thousand people perished in 1905 when the General Slocum steamship caught fire close to the island. The first American known to have typhoid fever, "Typhoid Mary" Mallon, was quarantined two years later and passed away here in 1938 from pneumonia. Currently a protected bird sanctuary, the island is always off limits to the general public.

12.New York Stock Exchange, New York City

Many of us are fascinated by what happens inside the New York Stock Exchange thanks to films like The Big Short and The Wolf of Wall Street.

Since the September 11th attacks, this well-known building has been off-limits to visitors, and now greater security makes it impossible to approach too closely. However, you can admire its beauty from the outside and see the recognizable

Several blocks away, you can visit the Federal Reserve Bank's gold vault and the statue of the Charging Bull.

13.The Knickerbocker Club, New York City

You may get lucky and get invited inside this magnificent Georgian mansion if you're one of the world's elite. Otherwise, this is the closest you'll ever come to The Knickerbocker Club, or the "Knick."

Franklin D. Roosevelt and businessman JP Morgan were notable former members of what is regarded as one of America's most exclusive societies. The club is so closed off that it doesn't even have a website, and its members are not allowed to talk about its activities with anyone else.

14.Robins Island, Suffolk County, New York

This private island, which is situated in Peconic Bay in the Hamptons, just off Long Island, is not just very valuable—it is also inaccessible. Business tycoon Louis Bacon has a 435-acre plot of land that is estimated to be worth £369 million ($500 million).

Even the local police force is unsure of what really takes place there.

15.Rikers Island, New York City

Between Queens and the Bronx, in the East River, towers the famed prison island. Since 1932, it has served as the location of New York City's primary jail complex, earning a bad reputation for violence and abuse.

One of America's most notorious prisons, Rikers, has housed inmates including Sid Vicious of the Sex Pistols and serial killer David Berkowitz, also known as Son of Sam. Perhaps it's for the best that visitors are not permitted nearby.

16.Abandoned Farmhouse, Seneca Lake, New York

This abandoned farmhouse on the east side of Seneca Lake, the largest of the Finger Lakes, might be enough to make you want to stay away after just one glance, yet the neighborhood residents have long been intrigued by the eerie structure.

The enigmatic property has been vacant for years, slowly being consumed by towering poison ivy vines. Vintage autos that are rusted and covered in vegetation just heighten the unease. Even now, it is a restricted private property.

17.North Brother Island in New York City

Between the island of Manhattan and the notorious Rikers Correctional Facility is a little island called North Brother Island. Almost no one is permitted on the site, where it has been abandoned since 1963, and you must acquire authorization from the city of New York, like Insider did in 2017.

The island now serves as a sanctuary for birds, but it also served as a ward for patients suffering from highly dangerous diseases like Typhoid Mary. Even a morgue exists.

North Brother Island won't contain any abandoned structures, despite how popular abandoned building exploring places are.

18.Diego Garcia, Chagos Islands, British Indian Ocean Territory

Diego Garcia, the largest of the Chagos Islands, is a crucial, if contentious, aspect of American security even though it is located within British Indian Ocean Territory.

In the 1970s, the US military started constructing secure facilities, including an air and naval base, drawing criticism from nations hoping to maintain the region's non-militarized status. Diego Garcia served as the launch pad for numerous air operations during the early 1990s Persian Gulf War, and it was also crucial at the beginning of the Iraq War in 2003.

The island is uninhabited and is still off-limits to everyone save for military personnel.

19.ADX Florence, Florence, Colorado

Could the ADX Florence be the safest structure in America?

The only "supermax" prison in the nation is located in Fremont County, Colorado, and it has extraordinarily stringent security standards. Prisoners judged too dangerous for regular detention reside there, and it is rumored that some of them spend up to 24 hours a day in solitary confinement.

In fact, the facility is so secure that there aren't many pictures of it. This image from 2021 depicts the exterior against an odd Rocky Mountain setting.

20.Dulce Base, Dulce, New Mexico

Rumors of livestock mutilation and extraterrestrial abductions tied to an underground lair under New Mexico's Archuleta Mesa mountain range have long plagued the tale of Dulce Base (pictured).

The location, which is reportedly a top-secret military station, is close to the little town of Dulce, and over the years, inhabitants have claimed to have heard unusual noises and seen mysterious lights emanating from the base.

A symposium to address the strange events is scheduled for June 2022. Some people think the station is jointly administered by humans and aliens.

21.Mount Weather, Bluemont, Virginia

This massive facility, operated by the Federal Emergency Management Agency, is situated on a 434-acre location and is staffed by 240 people. It supports emergency management operations.

The Mount Weather Emergency Operations Center purportedly contains an underground bunker with its own hospital, crematorium, and emergency power plant as well as significant communication lines to the White House.

Six significant disaster operations facilities are now located on Mount Weather, which is still off-limits to the general public.

22.Cheyenne Mountain Air Force Station, Colorado

You might be able to touch Cheyenne Mountain Air Force Station, which dominates the Cheyenne Mountain Complex, if you ever find yourself in Colorado's El Paso County. During the Cold War, this served as a command center for defense against the Soviet Union, and it is now reportedly a training facility for the US Air Force.

What happens inside is still somewhat of a mystery since it is hidden inside the mountain itself and is only accessible to those with the highest levels of security clearance.

23.Guantánamo Bay, Cuba

This infamous jail, which is part of the Guantanamo Bay Naval Station, is really located in Cuba but is a significant military prison for the United States.

The highly guarded, remote camp, where some prisoners are kept indefinitely, has come to be associated with torture and incarceration without charge. Even if you could, you definitely wouldn't want to visit this area because it has been shrouded in controversy since the first prisoners were moved to the prison camp in January 2002.
