Despite all the things we’ve learned about ancient history, there’s still many unexplained archaeological discoveries. Most discoveries give us a window into the past. However, there are some discoveries that defy popular knowledge about ancient civilizations and their capabilities. Like, how was Stonehenge built? What are the Nazca lines for? What’s the deal with the devil’s bible? But, just because we don’t understand something, doesn’t mean we can’t try and learn from it. Eventually, we’ll figure it out. In the meantime, it’s fun to enjoy the mystery of the past. Check out these 25 mysterious archaeological discoveries no one can explain.
The Sound Effects of Hypogeum Hal Saflieni
The Hypogeum Hal Saflieni temple in Malta is a prehistoric discovery dating 5,000 years ago. It’s also one of the only underground temples known from the bronze age. No one knows what the structure was used for but archaeologists guess it was a sanctuary for an oracle. Even more mysterious is the sound properties associated with the structure. Standing inside the hypogeum is like being inside a giant bell and amplifies sound throughout the entire structure. Did the ancient people who made the structure design it that way?
The Khatt Shebib
Discovered in 1948 by Sir Alec Kirkbride, the Khatt Shebib is an ancient wall stretching for 93 miles (150 kilometers) in Jordan. Since its discovery, the wall has left researchers with many unanswered questions including what it was used for and how old it is. In its current state, the wall is in ruins but may not have been too high when first built, indicating it wasn’t used for defense purposes but rather by ancient farmers.
The Devil's Bible
Codex Gigas, also called The Devil’s Bible, is the largest medieval manuscript in the world. Its size is so big it requires two people to lift it and includes the entire old and new testament plus two books by Josephus and The Chronicle of Bohemia by Cosmas. Who created the book is unknown but some think it was a monk shut away in seclusion for decades.
Located in Bolivia, Puma Punku is a site with massive stones carved with exacting precision. However, what puzzles archaeologists is the age of the stones. While dating has been a point of controversy, some saying they’re dated to 500 or 600 A.D. and others as far back as 15,000 B.C. It’s difficult to know how an ancient people cut the stones so precise that it looks like they used a diamond cutter.
The Longyou Caves
Discovered in 1992 by a curious local of the Longyou village, the Longyou Caves are a series of man-made underground structures that were once flooded. The caverns sink as deep as 100 feet. None of the caves are connected but they share thin walls. Dated back to 200 B.C., there is no record of the caves ever being built, making their purpose and origin a mystery.
