Petra: what it is
Petra grew rich on the incense and spice trade between Arabia and the Mediterranean. The Nabataeans carved hundreds of tombs, temples and houses into the surrounding cliffs, and built free-standing temples, theatres and colonnaded streets in the valley.
Visitors reach Al-Khazneh through the Siq, a winding gorge about 1.2 km long. The façade appears suddenly through a slit in the rock — an entrance experience that its designers may well have intended.

- 01
Carved from the top down
Masons cut a sheer face into the cliff, then carved the façade from the top, standing on the uncut rock below, so no scaffolding was needed. The interior is a plain square chamber.
- 02
Two storeys of borrowed classicism
The lower storey is a columned portico with a pediment; the upper storey has a round tholos flanked by broken pediments. These are Hellenistic forms from Alexandria, adapted by Nabataean taste.
- 03
A city designed around water
Petra gets very little rain but sudden floods. The Nabataeans diverted floodwater with a dam and tunnel at the Siq entrance and cut channels and cisterns into the rock to store water year-round.
Construction timeline
Nabataeans are recorded in the region; Petra becomes their capital.
Al-Khazneh is carved, most likely under King Aretas IV (9 BCE – 40 CE).
Rome annexes the Nabataean kingdom as the province of Arabia Petraea.
A major earthquake damages much of the city.
Swiss explorer Johann Ludwig Burckhardt reaches Petra in disguise, the first European known to do so in centuries.
Inscribed by UNESCO in 1985; in 2003 excavation reveals tombs beneath the Treasury's forecourt.
How the design changed
Bullet holes in the urn
Local legend held that the stone urn on top was full of treasure, which gave the building its name. The urn is pitted with bullet marks from people trying to break it open.
Buried and revealed
Floods and sediment raised the ground in front of the Treasury by several metres over the centuries; excavation lowered it again and uncovered the tombs below.
Who built it
Petra was carved by Nabataean masons for their kings and leading families. The Nabataeans wrote in an Aramaic script that developed into Arabic script, but no inscription names the Treasury's designer or confirms whose tomb it was.

Petra: questions people ask
Who built Petra's Treasury?
Nabataean masons carved it, most likely for King Aretas IV around the 1st century CE. No inscription names its designer or its owner.
Is the Treasury at Petra really a treasury?
No. Despite its name, which comes from a legend about treasure in the urn on top, it was probably a royal tomb or memorial temple.
How was Petra's Treasury carved?
From the top down: masons smoothed the cliff face and carved downward, standing on the rock beneath, so they did not need scaffolding.
When was Petra rediscovered?
Local Bedouin always knew it. For Europeans, Johann Ludwig Burckhardt reached Petra in 1812 and published his account.
