9 of the World's Most Ridiculously Secure Safes and Vaults

Original image

1. Fort Knox

Plan on breaking into Fort Knox? First, climb the four surrounding fences—two of which are electric—and then sneak past the armed sentinels lining the perimeter. Be sure to avoid the video cameras. Don’t waste time trying to blast through the granite walls—they are four feet thick and held together by 750 tons of reinforcing steel. If you get past the armed guards inside, plus the maze of locked doors, you’ll probably be stopped by the 22-ton vault door. Don’t despair. The vault can be opened, but only if you find all the staff members who know a small slice of the combination (you’ll need all of them, since nobody knows the whole thing.) Once you get inside the vault, you’ll have to break into the smaller vaults tucked inside, then you can start taking the 5000 tons of gold bullion stored in there. And do be careful when you leave: 30,000 soldiers from Fort Knox’s military camp will be anxiously awaiting you outside.

2. Svalbard Global Seed Vault

If Armageddon happens soon, any hope of bringing the world’s crops back is buried 390 feet under a Nordic mountain. The Svalbard Global Seed Vault on the island of Spitsbergen currently houses over 500,000 of the world’s plant species. The vault is 620 miles south of the North Pole and safeguarded by hundreds of miles of ocean, plus a couple thousand polar bears. It’s so deep, it’s resistant to a nuclear holocaust, not to mention severe earthquakes. It also sits 430 feet above sea level, safe from any possible sea-level rise. The three seed vaults lay behind four heavy steel doors. As long as the keys aren’t hidden under a doormat, our seeds should be safe from Doomsday.

3. Cheyenne Mountain

Cheyenne Mountain redefines the phrase “job security.” Employees work behind two 25-ton doors, which can withstand a 30-megaton blast. To put that into perspective, Fat Man—the bomb dropped on Nagasaki—would have to explode 1429 times to crack the entrance. The offices there are buried 2000 feet into the mountain’s granite, so far that air has to be pumped inside. That air, however, is the cleanest in the world. It is processed by a state-of-the-art system of chemical, biological, and nuclear filters. It’s no wonder why Cheyenne hosted the US Missile Warning Center and NORAD during the Cold War.

4. Iron Mountain

What do the charred remains of Flight 93, the original photo of Einstein sticking out his tongue, and Edison’s patent for the light bulb have in common? They’re all stowed under Iron Mountain. 200 feet below the ground, this retired limestone mine houses 1.7 million square feet worth of vaults. The US government is the biggest tenant, and the identities of 95% of vault owners are confidential. We do know that Warner Brothers, the Smithsonian Institution, and Corbis all have vaults there. Thousands of historic master recordings, photo negatives, and original film reels live here. Iron Mountain is also home to Room 48, a data center backing up some of America’s biggest companies. Two waves of armed guards protect the entrance, and it’s said they inspect guests so thoroughly that even the TSA would be embarrassed.

5. Federal Reserve Bank of New York

Blocks away from the panic of Wall Street, 25% of the world’s gold rests. At New York’s Federal Reserve Bank, over $270 billion of gold bullion hides in a sunken three-story bunker. Most of the gold, however, isn’t American; foreign nations own 98% of the stock. But that’s because they trust the Fed vault. After all, it’s 80 feet below ground, surrounded by solid rock from all sides, and surveyed by a fleet of expert marksmen. And to top it off, the 540,000 bars of gold are locked behind a 90-ton steel door.

6. Granite Mountain

Since 1965, Granite Mountain has safeguarded the Mormon Church’s genealogical library. The library is buried 600 feet beneath the mountain, where it contains 3.5 billion images—from census records to immigration papers—on microfilm. The documents were acquired through agreements with archives, libraries, and churches from over 100 countries. The archivists there duplicate and digitize old documents, which have been made public at websites like familysearch.com and ancestry.com. The facility is naturally climate controlled, but is also protected by armed guards and a 14-ton, nuclear-blast-resistant door. Chances are, somewhere inside, there’s a record with your name on it.

7. Teikoku Bank, Hiroshima

When the Enola Gay dropped Little Boy on Hiroshima, the city and its people were obliterated. But downtown, just a football field away from ground zero, the vault at Teikoku Bank sat undamaged. The exterior was fried but the interior was pristine. Mosler, the company that built the safe, saw the incident as a great marketing opportunity. For the next decade, it exploited the tragedy to boast about the quality of its products. Safe? Certainly. Tactful? Not so much.

8. Bank of England Gold Vault


It looks like something straight out of Indiana Jones: the UK’s largest gold vault—second in the world to the Fed in New York—stores 4,600 5152 tons of gold. The bombproof door is unlocked via a sophisticated voice recognition system, aided by multiple three-foot-long keys. (Last I checked, they can’t be duplicated at Lowes.) The bank won’t say how heavy the door is or how deep down the vault is buried, but we do know it has more floor space than London’s Tower 42, a 47-story building.

9. Bahnhof and WikiLeaks in Stockholm

The US State Department probably isn’t very fond of this safe house. Buried 100 feet beneath the streets of Stockholm, this old nuclear bunker is the gadfly of all data centers. That’s because the facility, owned by the Swedish internet provider Bahnhof, famously shelters the servers for WikiLeaks. Julian Assange’s most precious computers hide in this data bunker. Tucked behind a 1.5-foot steel door and driven by back-up generators that can go for weeks, WikiLeaks will keep breathing as long as it’s here.

5 Frank Lloyd Wright Homes You Can Buy Right Now

It can be hard for homeowners to sell Frank Lloyd Wright houses, even if they are live-in works of art. Some prospective owners don't want to deal with pilgrims or rubberneckers, while others simply aren't fans of Wright's style, or his penchant for building in far-flung locations. The upside? The architect's mega-fans have a better chance of scoring a genuine Wright original, occasionally at a relatively bargain price. From suburban Minnesota to rural New York, here are five drool-worthy Wright residences that you can purchase right now.

1. THE PAUL OLFELT HOUSE IN ST. LOUIS PARK, MINNESOTA

Address: 2206 Parklands Lane, St. Louis Park, Minnesota 55416

Asking Price: $1.3 million

History: In the 1950s, Wright designed one of his moderately priced Usonian homes for clients Paul and Helen Olfelt, who lived with their young children in St. Louis Park, Minnesota. A fan of Wright’s work, the couple had written the architect a letter requesting that he design their family one of his stylish single-family residences.

“We hoped for a refuge from the world for part of our day, a place where we could enjoy nature and the beauty of man’s creativeness in harmony with nature,” Olfelt, a radiologist, wrote in 1969 in the journal Northwest Architect. “We wanted a home that by virtue of its character would help us and our children be dissatisfied with the ordinary.”

Wright accepted the commission and briefly met with the Olfelts to discuss his vision, although he never visited the actual site—a tree-filled cul-de-sac—in person. The three-bedroom home's design was completed shortly before the architect’s death in 1959, and the Olfelts officially moved into the home in September 1960, and listed it for sale for the very first time in 2016. It’s still on the market, just waiting for a lucky Twin Cities area buyer to snap it up.

Bona Fides: The Paul Olfelt House comes equipped with a wood-burning fireplace; a fully equipped kitchen; and a master suite with both a dressing room/closet and an en suite three-quarter bath. It also includes many furniture pieces—including chairs, ottomans, desks, lamps, and tables—that Wright custom-designed for the home. Many, if not all, of these items are included the home’s sale price.

Fun Facts: The home has a basement, which is “rare for Wright homes,” a representative from Berg Larsen Group of Coldwell Banker Burnet tells Mental Floss. “He drew the line at the request for a bathroom; therefore, there’s an odd little commode in the unfinished storage area that we refer to as ‘plumbed for additional bathroom.’"

The basement also includes an office, which was designed for Olfelt; a play area for children (complete with swing); and a bar with banquette seating.

2. TIRRANNA IN NEW CANAAN, CONNECTICUT

Address: 432 Frogtown Road, New Canaan, Connecticut 06840

Asking Price: $7.2 million

History: "Tirranna" is an Australian aboriginal word meaning "running waters"—a fitting choice, considering that the U-shaped residence sits next to a pond fed by a nearby river and overlooks a tiny cascade. The home was built in the 1950s, and was one of Wright's very last houses built before his death.

Bona Fides: "Tirranna is one of the two or three biggest homes Wright ever built or designed, just from a size perspective," Houlihan Lawrence broker Doug Milne tells Mental Floss. "As you enter the main room, it goes from very low ceilings to soaring ceilings and glass, with Brazilian mahogany walls and ceilings that are just in miraculous condition."

Tirranna has seven bedrooms, and is surrounded by 15 acres of forest. Also on the grounds are a barn and stable, a greenhouse, a guest house, a swimming pool, a tennis court, a workshop, and gardens designed by Frank Okamura, the landscape architect for the Brooklyn Botanic Garden.

Fun Fact: If Tirranna achieves its $7.2 million asking price, it will set a record for the highest price ever paid for a Wright house. This money will go toward an important cause: mental health research.

Tirranna's last owner was the late businessman Ted Stanley, who died in early 2016 at the age of 84. But while Stanley became rich selling collectibles, his true passion ended up being medical philanthropy. It all started when Stanley's teenage son, Jonathan Stanley, was diagnosed with bipolar disorder in the late 1980s. His eventual recovery was largely due to being treated successfully with the right medicine. The experience turned Stanley into a staunch advocate for mental health research, and he spent the remainder of his life donating vast portions of his fortune to research institutions like the Broad Institute, a biomedical and genomic research center in Cambridge, Massachusetts.

The Broad Institute employs some of the world's top scientists, who research both the genetic and molecular causes of psychiatric disorders and potential treatments. “My son’s life was saved,” Stanley told The New York Times in 2014. "I would like to purchase that happy ending for other people."

When Stanley died in 2016, he left the Broad Institute much of his fortune. Tirranna's proceeds will also be directed toward the research center.

3. THE LOUIS PENFIELD HOUSE IN WILLOUGHBY HILLS, OHIO

Address: 2215 River Road, Willoughby Hills, Ohio 44094

Asking Price: $1.3 million

History: Designed by Wright and built in the mid 1950s, the Louis Penfield House is a nature lover's dream. The restored Usonian home sits atop a knoll overlooking the nearby Chagrin River, and across the street from protected forest, creeks, and hiking trails. The home was commissioned by high school art teacher Louis Penfield and his wife, Pauline, but has operated as a vacation rental house since 2003. New owners can opt to keep renting it or to use the home as a private residence.

Bona Fides: The three-bedroom, two-story home comes complete with Wright-designed furniture, which is included in the cost of sale. Owners can also say bye-bye to heating bills, as the home has a radiant-floor heating system fueled by one of two natural gas wells on the property. And just in case you were looking for even more bragging rights, the home is listed on the National Register of Historic Places.

Plus, prospective buyers have the chance to score two Wright homes for the price of one (well, kind of): "The last original Wright building site in the world is located adjacent to the Penfield House," and is included in the sale, listing agent Karen Eagle of Howard Hanna tells Mental Floss. "The building plans for Wright’s last residential commission, called Riverrock, are owned by the Penfields. The house is historically significant. It is design number 5909, and was on Wright’s drawing board when he died. The Penfields received the plans shortly after his death in April 1959."

Fun Fact: "Louis Penfield was nearly 7 feet tall," Eagle says. "The home was designed to accommodate his tall stature. Frank Lloyd Wright's ceilings are typically low. The staircase is pretty interesting too, since it accommodates for height."

According to legend, Penfield visited Wright's Wisconsin studio and challenged the architect to build a custom home for his towering frame. Wright accepted the dare, and mailed his new client a preliminary drawing six months later. The rest, as they say, is history.

4. THE F.B. HENDERSON HOUSE IN ELMHURST, ILLINOIS

Address: 301 South Kenilworth Avenue, Elmhurst, Illinois 60126

Asking Price: $1 million

History: Built in the early 1900s, the F.B. Henderson House is an early example of Wright's signature brand of Prairie style architecture. The architect built the home in conjunction with Chicago architect Webster Tomlinson, who briefly served as Wright's business partner. The two are both listed as the home's architects, although Tomlinson was reportedly more like the project's office manager and business agent.

Originally commissioned by client Frank Bignell Henderson in 1901, the home has been on and off the market for the past decade. That said, real estate agents tell Mental Floss that they've seen prospective buyers sniffing around as of late.

Bona Fides: Both the interior and exterior of the F.B. Henderson House have been recently restored, but the property still has plenty of original mid-century charm to spare. And if charm alone won't do, there's also three fireplaces, a wine cellar, and an expansive terrace overlooking the lawn.

"There is a real open feel on the first floor," agent Marilyn Fisher of LW Reedy Real Estate tells Mental Floss. "It’s a massive space. It has a huge foyer as you walk in, and then when you come into the main part of the house, you have a really big living room. On either side of the living room are mirror-image rooms. One side is half of an octagon, and the other side is the other half, making for a wide expanse. It's a very dramatic look."

Fun Fact: The F.B. Henderson House has more than 80 art glass, or stained glass, windows. Wright often referred to these mini works of art as "light screens," as they evoked the look of sliding Japanese shoji screens.

5. THE MASSARO HOUSE IN PUTNAM COUNTY, NEW YORK

Address: Petra Island, Lake Mahopac, Carmel, New York

Asking Price: $14.92 million

History: Some Wright purists turn up their noses at the Massaro House, in spite of its spectacular location (on a 10-acre private island), its spectacular design (a 5000-square-foot home with a cantilevered deck that practically puts Fallingwater to shame), and its spectacular scenery (did we mention it's on a lake?). They say it's just "inspired" by the architect, instead of truly being his original work.

Around 1950, engineer A.K. Chahroudi commissioned Wright to design him a dream home on the island, but the client wound up not being able to afford the planned project. Instead, Wright created a small guest cottage for his client. In 1996, sheet metal contractor Joe Massaro purchased Petra Island, and he also acquired Wright's original plans for the site, intending to fulfill the famous architect's ultimate vision.

With the help of architects and scholars, the Massaro House was completed around 2007. However, the Frank Lloyd Wright Foundation refuses to recognize it as an authentic Wright design, as they're not happy about some controversial design tweaks Massaro made to the plans.

Bona Fides: The home has geometric windows, a wraparound patio, and boulders integrated into the walls, giving it a natural feel. Other structures on the island include the aforementioned guest house and a tea house.

Fun Facts: If you own your own chopper, look no further than the Massaro House. "It has a helipad," Chadwick Ciocci, the CEO and founder of global real estate concierge Chilton & Chadwick, tells Mental Floss. "I don’t know of any other Frank Lloyd Wright homes that have that."

"Also very important is that the home is on a private heart-shaped island," Ciocci adds. (Really? We hadn't noticed.)

Want to Live Like Snow White? Buy This Cottage
Original image

In the 1970s, one family in Washington state decided to bring the magic of Snow White home—and we don't mean on VHS. (That didn't come out until 1994, anyway.) They built a replica of the cottage from Snow White and the Seven Dwarfs in Olalla, across Puget Sound from Seattle. And now, you can take over Snow White’s housekeeping duties—the house is for sale, as we spotted on the listing site TopTenRealEstateDeals.com.

The house looks straight out of a Disneyland attraction, with a winding staircase seemingly built into a tree, hand-built doors of different sizes with giant iron hinges, stone details and exposed beams, a wood stove, and a rounded interior that “wraps around you like a big hug,” according to the listing. (Good luck hanging shelves, though.) Honestly, the shiny walls look a little plastic, but it’s all part of the Disneyfied appeal.

The interior of the first floor shows a stone oven, a fake tree, and a chandelier.

A spacious room with two different sized doorways looking through to another room.

A bedroom has a mattress tucked into a cave-like nook.

An exterior view of the cottage through an overgrown garden.

Unlike the Seven Dwarfs’ pad, though, this comes with a hot tub and high-speed internet, not to mention a washer and dryer to save any future Snow Whites the effort of hanging laundry. And there’s no need for everyone to sleep side-by-side in twin beds. The two-story “cottage” has four bedrooms and five baths.

The 2800-square-foot house comes on a five-acre gated property. Outside, there’s a sweet tree house with a fireplace inside, a wooden bridge over a creek, and a garden with fruit trees.

It’s $775,000, zero dwarfs included. You can see the listing here.
