Can you crack the code? Treasure mysteries that remain unsolved

If you were asked about your most priceless possession, what’s the first thing that pops into mind? And what would you do to protect it? Since time immemorial, pirates and princes, captains and mysterious men have acquired wealth and done the impossible to defend it. So much so that from treasure chests to gold-filled trains, some riches were hidden so well that they have vanished to this day. Let’s find out about 10 of the most unbelievable lost treasures around the world and try to imagine what we’d do if we found them.

The Amber Room, often called "The Eighth Wonder of the World", was an 18th-century opulent chamber made of six amber panels, gold leaf, and mirrors. It was commissioned in 1701 for Prussia’s King Frederick, and later gifted to Russia’s Tsar Peter the Great in 1716.

It was then installed in the Catherine Palace in Tsarskoye Selo, Russia, until it was dismantled by German troops in just 36 hours in 1941 and moved to Königsberg Castle in East Prussia. Since 1945, amid Allied bombings, the Amber Room has disappeared without a trace, believed to have either been burned, buried, or sunk in the Baltic Sea.

It’s an armored 150-meter-long convoy rumored to be filled with 300 tons of gold, jewels, and stolen art. Allegedly, it vanished in May 1945 inside a secret network of unfinished tunnels in the Owl Mountains, near Walbrzych, Poland, as German forces fled the advancing Soviet Army.

Explorers and treasure hunters have launched many high-profile searches using groundbreaking technology to locate the train, but nothing has ever been found.

The Flor de la Mar ("Flower of the Sea") is a legendary Portuguese ship that sank in November of 1511, on its return from conquering a wealthy hub, now known as Malaysia. With it, an immense fortune estimated at $2.6 billion sank to the bottom of the ocean and was never recovered, making it one of the richest shipwrecks in history.

Over the centuries, countless marine salvage companies have attempted to recover the treasure, although political disputes over salvage rights between Indonesia, Malaysia, and Portugal have continuously interrupted such expeditions.

The Treasure of Lima is a massive fortune of gold, silver, and jewels (including a life-size solid gold statue of the Virgin Mary), valued at up to $208 million and missing since 1820.

It was stolen by British Captain William Thompson, who had originally been tasked with protecting the Spanish treasures and allegedly buried them on Cocos Island off Costa Rica, never to be seen again. When captured, he agreed to lead the Spanish forces to the gold, but instead escaped with his first mate into the thick jungle and vanished forever.

The infamous pirate Edward Teach, also known as Blackbeard, left behind a treasure no one has ever found. He terrorized the Atlantic Coast and the Caribbean, capturing numerous ships and stealing gold, silver, and valuable goods from them.

Modern estimates suggest that his riches would be worth $150 million. Before his death in November 1718, he claimed his wealth was hidden where "nobody knows but me and the Devil."

The Oak Island Money Pit is a centuries-old mystery of buried treasure filled with traps and tunnels, located in Nova Scotia, Canada. It began in 1796 when teenager Daniel McGinnis found a circular depression under a tree and started digging with friends.

As they dug, they began to find oak logs 10 feet down, pointing to a man-made shaft, but water from a storm later flooded the pit. Rumors suggest there is a vault with pirate gold from Captain Kidd, Spanish artifacts, or Marie Antoinette's jewels, as searchers have found tropical coconut fibers and fragments of gold chain there; skeptics suggest it might’ve just been a natural sinkhole all along.

Of the 50 Imperial Fabergé Easter eggs created for the Russian royal family, up to eight remain unaccounted for. Notable missing pieces include the "Nécessaire Egg" (1889), the "Cherub with Chariot" (1888), and the "Hen with Sapphire Pendant" (1886).

While many were lost or stolen during the 1917 Russian Revolution, miraculous findings, such as the "Third Imperial Egg" recovered at a U.S. flea market after a century-long disappearance, keep collectors' hopes alive.

The Honjō Masamune Sword is a priceless Japanese samurai weapon that was lost after World War II. It is considered one of the finest blades ever forged by the master swordsmith Gorō Nyūdō Masamune, and remains a priceless cultural symbol of power.

Designated an official Japanese National Treasure in 1939, many experts remain hopeful it might appear in a private collection or attic.

The Beale Ciphers Treasure is a renowned unrecovered fortune of gold, silver, and jewels, with an estimated value of over $65 million.

In 1820, a mysterious man named Thomas J. Beale checked into a hotel in Lynchburg, Virginia, and left a locked iron box with an innkeeper, alongside three encoded messages. If cracked, they supposedly reveal the hidden fortune. For now, only one has been decoded. Some experts allege the entire mystery is a hoax, while others continue to try to decipher the codes to this day.

The Lost Dutchman’s Gold Mine is a famous, undiscovered gold deposit, said to be hidden somewhere near Apache Junction, in Arizona’s Superstition Mountains.

Legend claims it was found by Jacob Waltz, a German immigrant (misidentified as Dutch due to the old use of the term "Deutsch"), who settled in Arizona in the 19th century and supposedly kept its location secret before dying in 1891, except for the verbal hints he allegedly gave to his neighbor Julia Thomas, sparking modern treasure hunting to this day.

Facts you didn't know you needed

Is the day longer for your pet? Mind-blowing facts you need to know

Adults often assume they already understand the world, but there’s always something new to surprise us! Did you know that clouds actually have weight? Or that the day is longer for some animals? And that’s just the beginning. From hidden functions of your organs to the true color of the universe, today you’ll learn 10 fascinating facts you probably never thought to ask, but will make you sound impressively smart in your next conversation!

Unlike humans, animals don’t experience a shared "present" in quite the same way. Instead, their sense of time is tied to the rhythms of their own bodies. For very small animals with fast metabolisms like parrots, hamsters, or guinea pigs, time actually seems to pass more slowly. In a sense, they live in slow motion because their faster-working nervous systems allow them to process sensory information at a fast speed.

What if someone commits a crime and tries to blame their identical twin? Have you ever wondered about that? It’s a valid question; after all, identical twins not only look alike, they also share the same DNA. But here’s the surprising part: if investigators check fingerprints, the innocent twin could be cleared. That’s because, despite their nearly identical DNA, twins have unique fingerprints, shaped by subtle genetic and environmental factors in the womb.

You’ve probably spent time lying on the grass, watching clouds drift across the sky. They look light, fluffy, almost like cotton candy, and it’s hard to imagine them as heavy objects. But the truth is surprising: clouds are incredibly heavy. An average cumulus cloud can weigh around 1 million pounds! That impressive weight comes from the billions of tiny water droplets suspended in the air. So, how do they float? It’s because each droplet is extremely small and falls very slowly, while rising warm air currents help keep the cloud suspended above us.

Most of us have a rough image of the world map in our minds. But we have something to tell you: most maps aren’t completely accurate. Because the Earth is a sphere, cartographers have to distort some areas to represent it on a flat surface. On Mercator projection maps, countries near the poles appear much larger than they really are, while countries near the equator look smaller in comparison. For example, Alaska looks about the same size as Brazil, but in reality, Brazil is nearly five times larger!

Most people don’t realize that there’s actually a name for the color of the universe. Strange, right? But it’s true! Astronomers who studied the light from thousands of galaxies discovered that if you blend all the colors from the observable universe, the result is a soft, beige-ish white shade, famously named "Cosmic Latte" in 2002.

With 50 states, there’s no shortage of variety in their names. Almost every letter of the English alphabet appears at least once, except for one: Q, which is completely absent. In addition to this, there’s another surprisingly rare letter: J. While it isn’t entirely missing like Q, it only appears in one state, New Jersey.

Although we don’t notice it, indeed, the Earth’s rotation is gradually slowing. This happens because tidal friction, caused by the Moon’s gravitational pull on our oceans, creates a subtle drag on the planet’s spin. As a result, days are getting longer, but very gradually: by only about 1.7 milliseconds per century.

Do you remember your last dream? Whether good or bad, dreams are a constant part of sleep, but not everyone experiences them in the same way. Deaf people who use sign language in their daily lives often communicate through signs in their dreams, too. Meanwhile, blind people tend to have dreams rich in sounds, smells, and tactile sensations, using these other senses to experience the dream world.

We’re used to seeing hippos covered in mud, splashing in water, or barely peeking above the surface. But here’s a surprise: hippos can’t actually swim! That’s right. Because of their huge, heavy bodies, they don’t float or paddle like most animals. Instead, they walk or run along the riverbed.

Can your brain really "eat" itself? Well, close, but not exactly. There’s a process called phagocytosis, carried out by specialized immune cells in the brain known as microglia. These cells engulf and remove debris, dead cells, and other unwanted material. But don’t worry; it’s safe! The mechanisms exist to protect, repair, and maintain your brain.
