Petra Quiz: Test Your Knowledge of Jordan's Ancient Rose-Red City

Petra: The Lost City of Stone

Petra is one of the most extraordinary archaeological sites in the world — an ancient city carved directly into rose-red sandstone cliffs in the desert mountains of southern Jordan. For roughly 2,400 years, this remarkable place has stood as a testament to human engineering, artistic vision, and the power of trade-route civilizations to create wealth and beauty in the most unlikely places. Built by the Nabataean Arabs from around the 4th century BCE, Petra served as the capital of an empire that controlled the lucrative incense trade running from southern Arabia to the Mediterranean and Egypt. At its peak in the 1st century CE, Petra likely held 30,000 people — an astonishing population for a desert city without a major river, sustained instead by sophisticated water management systems that captured and stored every drop of rare rainfall. The Nabataeans carved monumental tomb facades, temples, theaters, and dwellings directly into the sandstone cliffs, creating a city where architecture and natural landscape merged seamlessly. Petra's most famous monument, Al-Khazneh ('The Treasury'), gained global fame when it appeared in Indiana Jones and the Last Crusade as the resting place of the Holy Grail. The Treasury's classical facade — with its Corinthian columns, mythological figures, and rose-colored stone — has become one of the most photographed sites on Earth. Beyond the Treasury, Petra contains hundreds of other monuments including the towering Monastery (Ad Deir), the Royal Tombs, the Roman Theatre, the Great Temple, and a vast network of streets, gardens, and residential areas. The Petra quiz on this page tests your knowledge of this remarkable place — its history, its builders, its monuments, its rediscovery, and its modern status as a UNESCO World Heritage Site and one of the New Seven Wonders. Whether you've visited Petra, dream of going, or are simply curious about ancient civilizations, you'll find questions ranging from approachable to genuinely challenging.

The Nabataean Civilization

The Nabataeans were Arab nomads who emerged from the Arabian Peninsula around the 6th century BCE and established themselves in the region around modern southern Jordan, southern Israel, the Sinai Peninsula, and parts of Saudi Arabia. They are first mentioned in historical records around 312 BCE when the Greek historian Diodorus Siculus described their conflicts with Antigonus I, one of Alexander the Great's successors. Initially, the Nabataeans were transhumant herders who supplemented their livelihood by raiding caravans crossing through the desert. Their genius was in recognizing that the trade routes themselves were a more sustainable source of wealth than raiding them. By the late 4th century BCE, they had established themselves as the masters of the Incense Route — the camel caravan trade carrying frankincense, myrrh, and other precious spices from southern Arabia (modern Yemen and Oman) north through Petra and on to Mediterranean ports like Gaza. Frankincense and myrrh were essential for religious rituals, embalming, perfumes, and medicines throughout the ancient world. Their economic value was enormous — frankincense's price has been compared to that of gold in equivalent weight. Petra's Nabataeans charged tolls and provided water, supplies, and protection to caravans, accumulating extraordinary wealth. They expanded their territory and influence, eventually controlling territory from northern Arabia to Damascus. Their kingdom prospered under kings whose names appear on monuments and coins — Aretas I, Aretas II, Aretas III, and most famously Aretas IV (9 BCE - 40 CE), under whose reign Petra reached its architectural and cultural peak. The Nabataeans developed their own distinctive script (an evolution of Aramaic that influenced what became modern Arabic), their own religious system blending Arab and Mediterranean influences, and their own artistic style that combined Greek, Egyptian, and indigenous elements.

Building a City in Stone

Petra's most distinctive feature is its dramatic carved architecture — facades cut directly into living rock rather than constructed with masonry. The Nabataeans developed exceptional skills at carving monumental structures into the soft sandstone cliffs surrounding their valley capital. Most of these carved structures were tombs — the most famous being Al-Khazneh ('The Treasury'), thought to be a royal tomb dating to around the 1st century CE, possibly for King Aretas IV or his son Obodas III. Al-Khazneh stands 39 meters (128 feet) tall, with a Greek-influenced classical facade featuring Corinthian columns, a tholos (a round temple-like structure on the upper level), and statues of mythological figures. The carving was done from the top down — laborers removed material starting at the highest point and working downward, leaving completed sections behind them. The reddish-pink color comes from iron oxide in the sandstone, varied by the natural striations and bedding of the rock. Beyond the Treasury, hundreds of other tombs of varying sizes line the cliff faces. The Royal Tombs — the Urn Tomb, Silk Tomb, Corinthian Tomb, and Palace Tomb — feature elaborate facades visible from far across the valley. Ad Deir ('The Monastery') is even larger than the Treasury — 50 meters tall — and sits high in the mountains above Petra, accessible only by an 800-step climb. Despite its name (given by later Christian inhabitants who used it as a chapel), it was probably a temple or assembly hall. Beyond carved monuments, Petra had constructed buildings as well — the Great Temple, the Qasr al-Bint, the Roman Theatre (carved into the rock but functioning as a typical Roman theatre seating 8,500), markets, and residential areas. The combination of carved facades and constructed buildings created a uniquely integrated urban landscape where architecture and natural rock merged.

The Sophisticated Water Engineering

Petra's most remarkable engineering achievement was its water system. The Nabataeans transformed a desert valley receiving only 100-150mm of rainfall annually into a thriving city supporting tens of thousands of people, lush gardens, and visiting trade caravans. They accomplished this through what may be the most sophisticated ancient water management system ever devised. Multiple hydraulic technologies worked together. Dams (sadds) were constructed across wadis (seasonal water courses) to capture flash flooding before it could destructively cascade through the city. Cisterns of various sizes — some carved into rock, some constructed — stored water for dry seasons. Ceramic pipes ran throughout the city, distributing water under pressure to fountains, public baths, gardens, and domestic uses. Channels carved into rock face moved water along precise gradients. Settling tanks removed sediment before water reached storage. Filtration systems ensured drinkable quality. The Nabataeans understood enough about pressure, flow, and water quality to operate water systems comparable to those of major Roman cities. The Siq itself contains channel systems carved into both sides of the gorge, evidence of redundant water delivery to ensure supply security. Recent archaeological surveys have identified dozens of cisterns and water features across Petra and its surrounding hinterland. The system was so well-designed that even with drastically reduced precipitation in modern times, parts of it would still function if restored. The Nabataeans also developed agriculture in this seemingly inhospitable environment, terracing hillsides, capturing runoff for orchards, and growing crops including grapes, figs, and grains. The combination of trade wealth and water management transformed Petra into not just a transit point but a substantial cosmopolitan capital — a desert city that thrived where survival itself seemed unlikely.

Roman Annexation and the City's Decline

Petra's golden age came during the reign of Aretas IV (9 BCE - 40 CE), but Roman pressure had been building for decades. The Nabataeans had attempted to maintain independence by skillful diplomacy with both Rome and various neighbors, occasionally fighting alongside or against Roman armies depending on changing circumstances. In 106 CE, under Emperor Trajan, Rome annexed the Nabataean Kingdom and turned it into the Roman province of Arabia Petraea. The annexation was apparently peaceful, with no military resistance from the Nabataeans (whether by negotiation or simple recognition of overwhelming force is debated). Petra continued to thrive under Roman rule, with new construction continuing — the Roman Theatre likely dates to this period, as do various buildings in the city center. However, two factors began Petra's gradual decline. First, the Romans developed alternative trade routes, particularly maritime trade through the Red Sea that bypassed Petra entirely. Sea trade was faster, carried more cargo, and avoided the tolls of overland desert routes. Second, in 363 CE, a major earthquake devastated Petra, destroying many buildings and damaging the water management system that was essential to the city's existence. The earthquake's destruction proved difficult to fully repair, and the city's decline accelerated. By the 4th and 5th centuries CE, Petra's population had dramatically reduced. The Byzantine era saw some Christian repurposing — Ad Deir became a chapel, and a Byzantine church was built — but the city was a shadow of its former self. After the Islamic conquests of the 7th century CE, Petra was largely abandoned by sedentary populations. Bedouin groups continued to live in and around the ruins, but the city's architectural marvels were no longer maintained. Earthquakes, weathering, and time gradually wore down the monuments. By the medieval period, Petra had passed out of regional consciousness for the wider world, known primarily to local nomads.

The Rediscovery: Burckhardt's 1812 Visit

For over 600 years, Petra was effectively lost to the wider world. Local Bedouins always knew of the city — they used some of the cave dwellings as homes and pastured flocks in the area — but European geographers had no information about Petra's exact location or even its existence. The valley was within a region considered dangerous and difficult to access for foreign travelers. This changed on August 22, 1812, when Swiss explorer Johann Ludwig Burckhardt (born 1784, died 1817) became the first Westerner in modern times to enter Petra. Burckhardt was an extraordinary linguist and cultural chameleon. Working for the African Association (a British learned society), he had immersed himself in Arabic, Islamic culture, and Bedouin customs to the point that he could pass as a Muslim Arab pilgrim — adopting the name Sheikh Ibrahim Ibn Abdallah. Traveling between Damascus and Cairo, he heard local stories of an extraordinary lost city in the southern desert. Skeptical that a guide would take him directly, he convinced his guide that he wished to sacrifice a goat at the supposed nearby tomb of Aaron (brother of Moses, sacred in Islam). The guide reluctantly agreed to take him through the area. As they passed through the Siq and emerged before the Treasury, Burckhardt understood he was looking at a major archaeological discovery, but had to maintain his cover, jotting hasty notes when his guide was distracted. He spent only a single day at the site before continuing on. Burckhardt's published descriptions caused a sensation in European intellectual circles. Subsequent expeditions followed, with David Roberts's famous 1839 lithographs introducing Petra's visual splendor to a global audience. Edward Lear, Frédéric Auguste Bartholdi (later sculptor of the Statue of Liberty), and many others visited and recorded the site. By the late 19th century, Petra was firmly established as one of the great wonders of antiquity.

Modern Petra: Tourism, Conservation, and Cinema

Petra's modern profile combines its status as Jordan's most important tourism site, a major UNESCO World Heritage location (since 1985), and a global cinematic icon. The city was voted one of the New Seven Wonders of the World in 2007 in a global online poll, joining the Great Wall of China, Christ the Redeemer in Rio, Machu Picchu, the Roman Colosseum, the Taj Mahal, and Chichen Itza. Petra is Jordan's flagship tourism destination, attracting 800,000 to 1+ million visitors annually before the COVID-19 pandemic. Tourism contributes billions of dollars to Jordan's economy and employs many thousands directly and indirectly. The site is administered by the Petra Development and Tourism Region Authority. Visitors typically enter through the Bab as-Siq area, walk through the Siq (1.2 km), and emerge before the Treasury — a journey designed to recreate the original arrival experience. The full site spans 264 square kilometers and a thorough visit requires multiple days. Indiana Jones and the Last Crusade (1989) cemented Petra's place in popular culture by featuring the Treasury's facade as the entrance to the Canyon of the Crescent Moon, the resting place of the Holy Grail. The film's helicopter shots through the Siq remain among cinema's most memorable establishing shots. Other films featuring Petra include The Mummy Returns, Transformers: Revenge of the Fallen, and Aladdin (2019, partly inspired by the architecture). Conservation challenges remain significant. The sandstone, while beautiful, is soft and continues to erode. Foot traffic from millions of visitors damages stone surfaces. Salt crystallization, water seepage, and seasonal flooding all threaten monuments. Climate change has increased flash flooding intensity. UNESCO and international partnerships fund ongoing conservation work. The Bedouin community traditionally lived within Petra's caves and tombs but were relocated in 1985 to the new village of Umm Sayhoun nearby — a controversial decision that has drawn criticism but has been justified as essential for site preservation. Many Bedouins continue to work at Petra as guides, vendors, and animal handlers (camels and donkeys for tourist transport).

Recent Discoveries and Ongoing Mysteries

Despite over 200 years of European archaeological attention, Petra continues to reveal new secrets. Drone surveys, ground-penetrating radar, satellite imaging, and other modern technologies have produced extraordinary discoveries. In 2016, a major previously unknown structure was identified using satellite imagery — a large platform with monumental staircase, possibly a ceremonial site, near the city center. This discovery surprised researchers who had assumed the central city was thoroughly mapped. Underground exploration has revealed hundreds of unknown tombs, water cisterns, and storage facilities. Geological surveys have identified ancient earthquake damage that revealed structural details previously unknown. The relationships between Petra's monuments — which are royal tombs, which are temples, which served other functions — remain partially debated. Recent dating has shown some monuments are older or younger than previously believed. The 2007 announcement of fragmentary scrolls discovered in a tomb (eventually known as the Petra Papyri) provided rare written sources for daily life in Byzantine Petra. Thousands of small artifacts continue to be cataloged, providing insights into Nabataean trade networks, religious practices, and daily life. Active archaeological projects involve teams from the United States, Britain, France, Germany, Switzerland, and Jordan. The Brown University Petra Great Temple Excavations, the American Center of Oriental Research, and various university programs maintain long-term presence. Beyond archaeology, ongoing scholarship covers Nabataean economics (how the Incense Route's wealth flowed through the city), water management (modern engineers study Nabataean systems for sustainable arid-region principles), iconography (the meanings of carvings, statues, and architectural details), and ethnography (the Bedouin communities living in and near Petra for centuries). Climate change presents both threats (increased flash flooding, erosion) and opportunities (some discoveries result from new exposed surfaces). Petra's continuing secrets ensure it will remain a major archaeological priority for generations to come — a city that has revealed only a fraction of what it knows.
