2000 Years Old City Found Hidden in the Desert! The Story of Petra’s Secrets

There’s a world-famous city carved into the rose-red cliffs of Jordan that has captured the imagination of travelers, historians, and filmmakers. Petra, also known as the “Lost City,” hides secrets of ancient engineering and culture in one of the driest places on earth. It’s not just a popular tourist destination but a symbol of human innovation in the harshest conditions. Dive into the full story behind the rediscovery, mysterious builders, and survival strategies of Petra – the legendary city hidden in the desert for over 2,000 years.
The Discovery of an Ancient Wonder
In 1812, a Swiss adventurer named Johann Ludwig Burckhardt was wandering the Arabian desert. Disguised in local clothes, he ventured into unfamiliar territory and lost his way in a maze of cliffs. After walking about 1.5 kilometers between towering rocks, the narrow passage suddenly widened. There, he stood amazed at a jaw-dropping sight: a grand, ornate structure carved straight into the limestone mountain.
This ancient site, in what is now southern Jordan, seemed wildly out of place amid empty deserts. Rising 127 feet high, with columns and intricate patterns, the structure looked like a treasure from another age. Locals called this building Khazneh, meaning “treasury” in Arabic, hinting at legends of hidden riches.
From the outside, the Khazneh’s facade stuns with its pillars and delicate carvings. Yet inside, the room behind the impressive entrance is simple. There’s no great decoration, just plain stone walls showing raw natural beauty. Even so, Burckhardt could sense he had stumbled on something extraordinary.
He pressed on, weaving deeper among the rocks. Soon, new wonders appeared at every turn: grand amphitheaters, temple ruins, monumental tombs, and traces of a lost city carved high above the valley floor.
Exploring Petra: What Lies Beyond the Facade?
Petra is more than just one building. As Burckhardt explored, he found:
- A huge stone theater with room for around 6,000 people, carved directly from the rock.
- Pathways twisting past temple-like structures and stone ruins, signs of a bustling metropolis.
- Monuments on high cliffs, showing that Petra’s builders didn’t fear heights or hard work.
Who once lived here? Petra is at least 2,000 years old. In its golden era, this stone city thrived where survival seems almost impossible. How did residents live in a waterless wasteland? Why did they carve instead of build? And why did they finally walk away, leaving behind only sand and silent walls?
Key Features of Petra’s Architecture
- Tall, decorated pillars and columns starting at the mountain’s base
- Intricate carvings above grand entrances
- Massive theaters and temples
- Monuments positioned on sheer cliff faces
- A network of rooms, pathways, and tombs, all carved into solid rock
The Nabateans: Builders, Traders, and Mystery People
Who were the people behind Petra? Burckhardt remembered tales of a desert tribe that controlled the trade routes between China, India, Egypt, and Rome. These were the Nabateans, a group mentioned in both Greek and Roman history. They started as nomads, living in tents on the sands.
But how did a wandering tribe create such a majestic city out of stone? The transformation from tent-dwellers to master builders baffles even today’s experts. The Nabateans grew rich by trading silk, spices, and other valuable goods, hiding their wealth in secret mountain caches.
News of Petra’s discovery spread fast. Soon, archaeologists from all over the world arrived, hungry to piece together the story of this lost civilization. Researchers found that Nabatean builders didn’t just copy others; they invented unique methods and techniques, some of which have never been seen anywhere else.
How Petra Was Carved: The Unique Building Technique
Unlike most ancient builders, the Nabateans didn’t construct stone structures by stacking blocks upward. Instead, they carved their monuments top-down, directly into cliff faces.
Here’s how they tackled the massive projects like the Treasury:
- First, workers climbed high on the mountain, securing themselves on the cliff.
- They dug a horizontal shaft straight into the rock at the desired height.
- Standing inside the shaft, they began to carve out pillars, sculptures, and decorative designs from above.
- As they sculpted downward, stone debris piled up below the work area.
- When the upper half was finished, workers used the sloping pile of rubble to climb down and access the lower half of the design, finishing it from ground level.
This method gave them control over intricate details up high and reduced the risk of chunks breaking off as they worked. Modern sites don’t show evidence of scaffolding or platforms, just like in today’s large-scale construction. Instead, the Nabateans let gravity and skill do the heavy lifting.
Researchers also found a half-finished structure at Petra. Its top is complete, but the lower part remains untouched—a perfect clue to how the ancient carvers worked.
Inscriptions and Tombs: What the Stones Reveal
Petra holds many secrets, but written records are rare. Only a few inscriptions, written in Aramaic script, have been found on the site. This language was widely spoken in the Middle East around the time of Jesus.
One inscription calls a tomb “very sacred,” warning that nothing inside should ever be removed or changed. Inside these vaults, researchers found only simple shelves, likely used for placing the dead. In total, more than 800 burial chambers have been discovered throughout Petra’s hills.
For a while, many believed Petra was just a huge graveyard. But later finds, like living areas and evidence of a large population, showed it was once a vibrant city.

Water in the Wilderness: Hydraulic Genius of the Nabateans
How did up to 30,000 people survive in the middle of one of the world’s driest deserts? The answer: advanced water engineering.
Researchers discovered holes in the floor of Petra’s Great Temple, hinting at hidden water channels below. By using Ground Penetrating Radar (GPR), a tool that examines what’s under the surface by sending radio waves and measuring how they bounce, experts found a web of underground channels running beneath the city.
But where did the water come from? Petra is still one of the driest places on earth. Locals rely on Ain Musa, a natural spring about 8 km away. The real feat was bringing water from this spring across rocky terrain to the city.
Stone pipelines ran along narrow passageways, made in segments that locked together. The Nabateans understood water physics: they set pipes at a constant 4-degree tilt, carefully measured to keep water flowing without trapping air bubbles or causing leaks. Modern hydraulic scientists have only recently figured out that 4 degrees is almost perfect for this purpose.
The pipes show how seriously the Nabateans took water management. They even built ancient dams at several points around Petra to collect rain and guard against flash floods. These sudden floods could destroy in minutes what took centuries to build. Today, at least five ancient dams from Petra’s heyday still stand, partly preserved after 2,000 years.
Petra’s Water Network – At a Glance

- Advanced engineering: 4-degree angled pipelines prevent leaks and air blocks
- Ancient dams protect against flash floods and save water for dry times
Decline and Abandonment of Petra
History always moves on, and Petra’s story is no different. In 363 AD, a fierce earthquake struck the region. Records and the ruins themselves show that many buildings and dams were damaged or destroyed.
With dams broken, flash floods grew worse and washed away infrastructure. The clever water system that allowed Petra to thrive now sped up its fall. Water, once the city’s life, became its biggest problem.
As conditions worsened, trade routes shifted elsewhere. Traders chose easier, safer roads. One by one, Petra’s population left, seeking safer homes.
By the late centuries, Petra was all but empty—a ghost town swallowed up by the desert winds. After its rediscovery, the world once again marveled at its beauty.
In 1985, Petra received UNESCO World Heritage Site status, protecting its ruins for future generations. Its stunning facade even starred as the Holy Grail temple in the film Indiana Jones and the Last Crusade, giving the ancient city new fame.

Why Petra Still Fascinates Us
Petra’s story is a reminder of human creativity when faced with tough challenges. The Nabateans mastered stone carving, built an oasis without modern tools, and connected China, India, Egypt, and Rome through trade.
Though many mysteries linger—like what daily life was really like, and the full meaning of Petra’s inscriptions—the city continues to inspire curiosity. Historians and travelers alike return to Petra year after year to admire its beauty and search for stories left in the stones.
