In the early 18th century the King of Prussia gave the ultimate diplomatic gift to Peter the Great of Russia. It was an entire room completely covered in six tons of glowing fossilized tree sap. The wall panels were backed with pure gold leaf and decorated with intricate gemstone mosaics and giant mirrors. When lit by candlelight the entire chamber looked like it was trapped inside a giant drop of liquid sunshine.
People came from all over Europe just to stare at it. They called it the Eighth Wonder of the World. Today experts estimate those glowing golden walls would be worth roughly half a billion dollars. But you cannot go see the original room today. It was stolen during the chaos of World War II and completely vanished from the face of the Earth.
The Worst Disguise In History

When Adolf Hitler launched his massive invasion of the Soviet Union in 1941 his troops had strict orders to loot the greatest cultural treasures they could find. The Amber Room was at the very top of their list. As the German army pushed closer to the Catherine Palace outside of St. Petersburg the Russian museum curators completely panicked.
They tried to take the intricate panels off the walls to hide them in a safe place. But the amber had dried out over a couple of centuries and became incredibly fragile. The precious golden resin started crumbling into dust the second they touched it with their tools. So the desperate curators tried a ridiculous backup plan. They pasted cheap mundane wallpaper directly over the priceless panels hoping the invading army would just walk right past the room.
The trick failed instantly. The Nazi soldiers tore down the paper and brought in their own experts. They dismantled the entire masterpiece in just thirty six hours. They packed the glowing golden walls into twenty seven heavy wooden crates and shipped the massive fortune off to a castle museum in the German city of Königsberg.
A Trail That Goes Completely Cold

The room sat on display in that German castle for a couple of years. But the tide of the war eventually turned against the invaders. In August of 1944 massive Allied bombing raids completely leveled the city of Königsberg and turned the famous castle into a burning pile of rubble. When the Soviet army finally rolled into the smoking ruins a few months later they searched frantically for their stolen treasure.
They found absolutely nothing. The massive heavy crates of amber were completely gone. This total disappearance sparked one of the greatest treasure hunts in human history.
Some historians believe the simplest answer is the brutal truth. They think the wooden crates and the dry brittle amber simply burned to ashes during the massive firebombs. But other researchers refuse to accept that such a massive fortune could just evaporate without a single trace.
The Endless Search For The Gold

Wild theories have popped up constantly over the last seventy years. Some people believe the Nazis secretly loaded the crates onto a massive transport ship just days before the city fell. That specific ship was sunk by Soviet torpedoes in the freezing Baltic Sea taking all its secret cargo to the bottom of the ocean.
Other treasure hunters have spent their entire life savings drilling into secret underground bunkers and abandoned salt mines across modern day Germany and Poland. They are completely convinced that rogue Nazi officers stashed the crates deep underground to wait out the end of the war.
There is even a massive conspiracy theory that the Russian government actually found the destroyed pieces in the castle basement. The theory claims the Soviets kept quiet about the accidental destruction so they could keep using the stolen room as a powerful piece of political propaganda during the Cold War. A stunning replica was eventually built in Russia but the true fate of the original glowing walls remains a completely unsolved puzzle.
