Carved into the rose colored sandstone mountains of ancient Jordan, it served as the political and commercial center of the Nabatean Kingdom, an Arab state that prospered by controlling trade across the deserts of the Middle East. Although Petra is often imagined as an isolated collection of monumental tombs, it was actually a large sophisticated city with temples, markets, houses, workshops and an elaborate water system. To understand why Petra was built, we need to understand the people who built it. The Nabateans. The region around Petra was inhabited long before the city ever reached prominence. Archaeological evidence shows human occupation in the area dating back to prehistoric times. Nearby settlements contain remains from the Neolithic period, when some of the earliest farming communities in the region developed during the Bronze and Iron Ages. The territory formed part of the cultural world of southeastern Transjordan, that being the lands just east of the Jordan River. By the first millennium BC it was associated with the kingdom of Edom, whose inhabitants controlled parts of the mountainous region south of the Dead Sea. The precise relationship between the Edomites and the later Nabateans remains unclear. Petra was not simply an Edomite city that the Nabataeans inherited. Rather, the Nabateans gradually established themselves in the region that had previously been occupied by Edomite communities and other peoples. The Nabateans were an Arab speaking people whose early history is very poorly documented. They appear to have originated among nomadic or semi nomadic communities living in northern Arabia. Over time they moved into southern Jordan and the Negev Desert where they became involved in the caravan trade. The Nabateans did not leave behind a written history of their own. Most knowledge about their early development comes from archaeology, inscriptions, coins and accounts written by Greek and Roman authors. Their language was Arabic, but their formal inscriptions were usually written in a form of Aramaic. Nabatean script later contributed to the development of the Arabic alphabetical. By the late 4th century BC, the Nabateans were already wealthy and organized enough to attract the attention of the successors of Alexander the great. In 312 BC, Antigonus I monothalmus, one of Alexander's former generals, ordered an attack on the Nabateans. According to the Greek historian Diodorus Sekoulis, the Nabateans were able to escape into the desert and defeat the forces that were sent against them. Petra probably developed gradually rather than being founded at a single moment. During the 3rd and 2nd centuries BC the Nabateans increasingly settled in permanent communities while continuing to control trade routes through the desert. Petra became their principal political and ceremonial center. Its Nabatean name, Rakmu, may have referred to the multicolored or pattern appearance of its sandstone cliffs. The etymology of the word Petra simply comes from the Greek word for rock. Petra lies in a rugged basin amongst the mountains of southern Jordan, roughly halfway between the Dead Sea and the Gulf of Aqaba. The surrounding sandstone cliffs contain narrow valleys and gorges that made the site both easily defensible, yet very difficult to approach. The best known entrance is the Siq, a small, narrow passage more than a kilometer long, bordered in places by cliffs nearly 80 meters high. The Siq was formed by geological forces and later modified by the Nabateans. They paved parts of the path, carved religious niches into its walls and installed channels that carried water towards the city. Petra's location offered several strategic advantages. The mountains protected it from attack, while routes through the surrounding valleys connected it with the Arabian Peninsula, the Mediterranean coast, the Damascus, Egypt and the Red Sea. The main disadvantage of the city was the shortage of reliable rainfall. The Nabateans overcame this problem through one of the most advanced water management systems in the ancient world. But more on that in a bit. The city's position allowed the Nabateans to profit from the movement of goods between southern Arabia and the Mediterranean. Frankincense and myrrh from Arabia were highly valued for religious rituals, medicine, perfumes and funerary practices. Caravans also carried spices, textiles, metals, precious stones and luxury products. Originating as far away as India, East Africa and China, Petra became an important transfer point within this much larger commercial network. The Nabataeans didn't merely tax passing caravans. They provided water, security, animals, guides, lodging, storage and access to regional markets. Their knowledge of wells, springs, desert routes and seasonal conditions gave them a major advantage over rival powers. Petra was basically the ancient equivalent of an enormous truck stop located at the intersection of several major interstate highways. By the second century bc, the Nabateans had established a formal monarchy. The first clearly documented Nabatean king was Aretaeus I. His successors expanded Nabataean territory and turned Petra into the capital of a significant regional kingdom. At its greatest extent, Nabatean power reached north towards Damascus, west into the Negev and Sinai deserts, and south along the caravan routes of the Arabian peninsula. The important Nabataean city of Hegra in Saudi Arabia marked another major center of the kingdom. Hegra is also home to some fascinating stone carved buildings moving much like those in Petra. One of the kingdom's most important rulers was Aretaeus iii, who reigned during the first century bc. He intervened in the affairs of neighboring Judea and briefly gained control of Damascus. These Activities brought the Nabateans into increasing conflict with Rome. The Roman general Pompey reorganized much of the eastern Mediterranean after his campaigns in the sixties B.C. although the Nabataean kingdom retained its independence, it increasingly operated within a Roman dominated political Nabatean rulers paid tribute at various times, cooperated with Roman campaigns, and attempted to preserve their autonomy through diplomacy. Petra reached the height of its prosperity from approximately the first century BC through the first century. Much of the monumental architecture that's visible today all dates from this period, particularly from the reign of Aretaeus IV. From 9 BC until the year 40, Aretaeus IV called himself King of the Nabataeans and the lover of his people. During his long reign, the kingdom enjoyed economic prosperity, urban growth and an ambitious building program. Petra became a monumental capital that reflected both Nabataean traditions as well as influences from Greek, Egyptian, Mesopotamian and Roman worlds. The city's architect carved enormous facades directly into sandstone cliffs. The workers probably began near the top and moved down using platforms, ropes, scaffolding picks and chisels. Carving from the top prevented falling stone from damaging completed sections that were below. The facades often combined classical columns, triangular pediments, decorative urns, eagles, human figures and symbols associated with death and the afterlife. Yet these designs were not simple imitations of Greek or Roman architecture. They were part of a distinctive Nabataean visual language that borrowed forms and rearranged them according to local tastes. The most famous monument in Petra is Al Khazni, meaning the Treasury. It appears dramatically at the end of the Sikh, where its elaborate facade is carved into a tall cliff. It's literally the first thing you see when you enter Petra, and it is often the only thing that most people see because they don't go any further. If you've ever seen Indiana Jones and the Last Crusade, this is the image that you're probably familiar with. Despite its modern name, the treasury was probably not used to store money. It was most likely a royal tomb or funerary monument, possibly constructed during the reign of Aretaeus iv. The name comes from a later legend that treasure had been hidden inside the stone urn at the top of the facade. The treasury is heavily influenced by Greek architecture. This includes Corinthian columns, mythological figures, and a central round structure known as a tholos. The interior, however, is relatively plain. As with many structures in Petra, all of the effort was concentrated on the exterior rather than the interior. The precise identity of the person who was buried there remains unknown. Excavations around the monument have revealed additional burial chambers, but archaeologists continue to debate its function and its dating and its relationship to the Nabataean royal family. Petra contains hundreds of rock cut tombs. Some have simple entrances, while others possess enormous facades. The so called royal tombs include the Urn Tomb, the Silk Tomb, Corinthian Tomb and the Palace Tomb. Their modern names are descriptive and do not establish who was buried in them. Not every major monument was a tomb. The city contained important freestanding buildings including the Great Temple, the Temple of the Winged Lions and Qasr al Bint. Qasr al Bint was one of Petra's principal religious buildings and may have been associated with the chief Nabatean deity Dushara. Petra could not have supported a large population without careful control of water. Rainfall was limited and highly irregular, but sudden storms could send flash floods through narrow valleys. The Nabataeans constructed dams, reservoirs, cisterns and pipelines. They redirected flash floods away from inhabited areas while capturing runoff for later use. Channels carved along the sides of the Siq carried water into Petra, sometimes through ceramic pipes. The system supplied drinking water, public fountains, baths, agriculture, and possibly even ornamental pools. Water was not merely a survival necessity in a desert environment. Fountains and gardens were displays of political power and wealth. In the year 106, following the death of the last Nabataean king, Rabel II, the Roman Emperor Trajan annexed the kingdom. The annexation appears to have occurred with relatively little fighting, although there are few details surrounding it. Nabatean territory became the Roman province of Arabia Petraea. Roman rule did not immediately destroy Nabataean culture, but when Emperor Hadrian visited the city in the second century, it adopted the title Hadriani Petra. Petra's decline was gradual and had several causes. Rome increasingly encouraged maritime trade through the Red Sea, allowing goods from Arabia and India to travel by ship to Egyptian ports. This reduced the importance of overland caravan routes. Earthquakes repeatedly damaged Petra. A major earthquake in 363 damaged buildings and disrupted parts of the water system. Additional earthquakes struck the region during later centuries. Earthquake damage alone did not end urban life in Petra, but it compounded the effects of declining trade, changing political structures and the expense of maintaining the city's infrastructure. As the population decreased, fewer people were available to keep dams, channels and public buildings in working order. Some residential areas were totally abandoned, while others remained occupied on a smaller scale. Petra was never totally abandoned. Some Bedouin people lived in Petra well into the 20th century, but the city ceased to be a major population center and was forgotten by the rest of the world. Petra was known through classical and biblical literature, but its exact condition remained largely unknown outside of the region for centuries. During the Crusades and later periods, only a small number of outsiders ever reached the site. In 1812, the Swiss explorer Johann Ludwig Burckhardt became the first modern European traveler to publish a detailed eyewitness account of Petra. Burckhardt had studied Arabic and traveled in disguise as a Muslim merchant. Systematic archaeological work began in the late 19th and early 20th centuries, and excavations expanded greatly after the creation of the independent Kingdom of Jordan. Today, Petra is the most famous and visited tourist site in Jordan. Petra was designated a UNESCO World Heritage site in 1985, and in 2007, Petra was selected through an international popular vote as one of the new Seven Wonders of the World. I've been to Petra on three separate occasions and I highly recommend it to everyone. If you're there, I strongly suggest the Petra at Night Experience, where you can walk the Sikh by candlelight and experience the treasury underneath the stars. There's still a lot we don't know about Petra and the people who live there. Archaeologists still debate the purpose of individual monuments, the identities of those buried in the monuments, the exact size of the population, and the organization of Nabataean society. Yet what survives makes one point unmistakable. Petra was not an isolated desert curiosity. It was one of the greatest commercial, technological and cultural centers of the ancient Middle East.
