Petra: The Rose-Red City That Was Hidden From the Western World Until 1812

March 28, 2026 · 4 min read

The Fact

Petra, the ancient Nabataean city in Jordan carved from pink sandstone, was unknown to the Western world until 1812.

A City Built by Desert Traders

The Nabataeans were an Arab people who built one of the ancient world's most successful trading empires from their capital at Petra, located in a basin surrounded by steep sandstone mountains in what is now southern Jordan. From roughly the 4th century BC through the 1st century AD, the Nabataeans controlled the caravan routes carrying incense, spices, silk, and other luxury goods between Arabia, Egypt, the Mediterranean, and India. The wealth this commerce generated funded a city of remarkable architectural ambition.

Petra's defining feature is that it is not built but carved — excavated directly from the living rock of the sandstone cliffs surrounding the basin. The stone itself is extraordinary: swirling bands of red, orange, yellow, and purple, laid down over millions of years and exposed by erosion, gave Petra the epithet "the Rose-Red City" from a poem by John William Burgon. The Nabataeans used this stone not merely as a canvas but as a construction material in the most literal sense, cutting rooms, temples, tombs, and facades directly into the cliff faces.

The Siq and the Treasury

Petra is entered through the Siq, a narrow gorge approximately 1,200 meters long and in places only a few meters wide, with sandstone walls rising 90 meters on either side. The gorge was formed by tectonic forces rather than water erosion, and the Nabataeans enhanced it with carved water channels along both walls that brought water from springs into the city. Walking through the Siq builds anticipation through near-total enclosure, and the effect of emerging from its end to face the Treasury — the most famous of Petra's carved facades — is one of the great dramatic arrivals in world travel.

The Treasury, known in Arabic as Al-Khazneh, is approximately 40 meters wide and 43 meters tall, its facade elaborately carved with columns, statuary, and decorative elements in a style that combines Hellenistic Greek and Nabataean traditions. Despite its name — derived from a local legend that Pharaoh's treasure was hidden inside the stone urn at its summit — it was most likely a royal tomb or temple. The interior contains three simple rooms with no decoration: all the investment was in the facade.

Hidden in Plain Sight

After the Roman Empire annexed the Nabataean kingdom in 106 AD, Petra gradually declined as trade routes shifted. By the medieval period, the city was essentially abandoned by all but local Bedouin communities who had lived in the area for generations. Arab geographers and travelers knew of its existence, and the local population had never forgotten it, but sustained Western awareness of the site had been lost.

Johann Ludwig Burckhardt, a Swiss explorer traveling in 1812, had heard rumors of a remarkable ancient city in the region. Disguised as a Muslim pilgrim and claiming he needed to offer a sacrifice at a tomb in the area, he persuaded a local guide to lead him through the Siq. He was the first European in modern times to see Petra and reported its existence to the Western scholarly world, initiating the archaeological interest that eventually led to systematic study of the site.

Petra in the Modern World

Petra was designated a UNESCO World Heritage Site in 1985 and was named one of the New Seven Wonders of the World in 2007 by a global popular vote. It receives approximately one million visitors annually and is by far Jordan's most important tourist attraction, contributing substantially to the national economy.

Ongoing archaeological work continues to reveal new aspects of the city. Survey work using ground-penetrating radar and satellite imagery has identified structures beneath the surface that have not yet been excavated, suggesting that the full extent of Nabataean Petra is larger than the visible ruins indicate. A city that hid from the Western world for a millennium has not yet finished revealing itself.
