In the courtyard of CIA headquarters in Langley, Virginia, stands a curving wall of copper punched with more than 1,700 letters. It is called Kryptos, it was dedicated in November of 1990, and for thirty five years the best codebreakers on Earth have walked past it on their lunch break unable to read the last line.
The sculptor, Jim Sanborn, divided his message into four parts. The first three fell in the 1990s, cracked separately by an NSA team, a CIA analyst working on his own time, and a California computer scientist. One passage describes Howard Carter breaking through into the tomb of Tutankhamun. Another gives coordinates and asks, does Langley know about this, they should, it is buried out there somewhere.
The fourth part, just 97 characters, never broke. Sanborn released clues over the years, the words BERLIN, CLOCK, NORTHEAST and EAST. Nothing.
Then in 2025, with Sanborn nearing eighty, he announced he would auction the solution. Weeks before the sale, two researchers found the answer sitting in his papers at the Smithsonian archives, filed there by mistake. They had the plain text. They still do not know how the cipher works. The auction went ahead anyway and the secret sold for 962,500 dollars to an anonymous buyer.
And Sanborn has said for years that even when all four parts are read, there is a final riddle underneath them. Something about that courtyard. Something buried.
What if the real message was never meant for codebreakers at all.
An art puzzle, or something hidden in plain sight at the CIA?
What do you think about this? On May 20, 1967, a prospector in Manitoba walked up to a landed craft near Falcon Lake. It blasted him with hot gas and left a grid of burns on his chest matching its vents. Three governments investigated. Canada put it on a coin. Hoax, or the real thing?
What do you think about this? Serpent Mound in Ohio is a 1,348 foot snake of earth, its head aimed at the summer solstice sunset, its body built on the rim of an ancient meteor crater. One dating puts it right after Halley’s Comet in 1066. Sacred art, or a message for the sky?
What do you think about this? Since the early 1990s about two percent of people in Taos, New Mexico, hear a low hum like a distant diesel that never shuts off. In 1993 Los Alamos and Sandia scientists came to find it. Their instruments found nothing. Trick of the ear, or a hidden signal?
What do you think about this? In 1974 a retired air traffic controller cast footprints in Louisiana’s Honey Island Swamp: three webbed toes, a foot long. He had reported a seven foot gray haired creature with yellow eyes standing over a dead boar in 1963. Hoax, or the Letiche?
What do you think about this? For nearly three years beginning April 2, 1968, a glowing figure of a woman appeared on the roof of a church in Cairo, seen by crowds of tens of thousands, Christians and Muslims together, and caught in press photographs. Mass illusion, or a visitation?
What do you think about this? A 2,200 year old wooden bird dug up at Saqqara in 1898 has no legs, no feathers, straight wings and a tail that stands upright like the fin of an airplane. Some replicas glide. A child’s toy that looks like a plane, or a memory of something that flew?
