Then, in 1812, the unique ruins of Petra were “discovered” by Swiss explorer Johann Ludwig Burckhardt. He described the ruins of the once-great city in chronicles of his travels.
With the western world now aware of their existence, they soon attracted the interest of architects and scholars, among others. Starting in 1929, British archaeologists Agnes Conway and George Horsfield, as well as scholars Tawfiq Canaan and Ditlef Nielsen, launched a formal project to excavate and survey Petra.
Numerous findings have been made in the decades since, including the 1993 discovery of Greek scrolls dating to the Byzantine period as well as the more recent documentation via satellite imaging of a previously unknown monumental structure buried beneath the sands of the area.
When Petra was named a UNESCO World Heritage Site in 1985, Petra Bedouin tribespeople who had made homes for themselves within the city’s remaining ruins were forcibly relocated by the Jordanian government.
In the early 2000s, the site was named one of the “Seven New Wonders of the World,” leading to a spike in tourism. Since then, efforts have been made to protect the ruins of Petra from heavy tourism, as well as damage from floods, rain and other environmental factors.

It is impossible for anyone outside the highest levels of the White House and Pentagon to know whether a massive attack on Iran will begin within the next 72 hours.
But something is clearly happening.
The evidence is no longer based merely on anonymous social-media accounts tracking aircraft or interpreting unusual military movements. President Donald Trump has publicly confirmed that he is close to deciding whether to launch an attack on Iran that could be “bigger than ever before.” American and Israeli officials have reportedly said expanded combat operations could begin within days.
Trump has also declared that the United States will attack Iran’s deeply buried Pickaxe Mountain facility “very soon.” The underground complex near Natanz is believed by Israeli intelligence to contain thousands of centrifuges moved into tunnels hundreds of feet beneath the mountain.
These are not vague warnings about unspecified future consequences. They are descriptions of targets, weapons and operations that appear to be under active consideration.

When the tribe built Petra, though, they developed a unique system of conduits, dams and cisterns to harvest, store and distribute rainwater for year-round use.
At certain times of year, the area around the city was prone to flooding. However, the Nabateans were able to effectively control these floods using dams and, therefore, the city’s water supply.
This meant that they could reside in the city even during periods of drought. It also improved the crop yields of Nabatean farmers.

The Nabateans living and trading in Petra soon accumulated a significant amount of wealth, and an envious Greek Empire attacked the city in 312 B.C. This event marks the first reference to Petra in recorded history.
The Nabateans successfully fought back the Greek invaders by taking advantage of the mountainous terrain surrounding the city. The mountains effectively served as a natural wall, buttressing Petra.
However, the Greek incursion was not the last time the city would come under attack.
In fact, the Romans would invade Petra in 106 A.D., and ultimately forced the Nabateans to surrender. The Roman Empire annexed the newly gained territory and changed its name to Arabia Petraea.
They continued to rule over the city for more than 250 years until the middle of the fourth century A.D., when an earthquake destroyed many of its buildings. The Byzantines eventually took control of the region, and governed Petra for some 300 years.

The site is considered significant by historians and archeologists alike because of its beautiful rock-cut architecture and innovative water management system, the latter of which made the region inhabitable, given that it is surrounded by desert and rugged, mountainous terrain.
Petra has also been referred to as the “Rose City” because of the color of the stones used in its buildings. It was named a UNESCO World Heritage Site in 1985.
