A ring of high cliffs at the edge of the desert encloses the city, leaving a single narrow gorge as the entrance.
Southern Jordan — Rock-cut ancient city ruins.
First read the façades cut into the sandstone, then turn back to find the chisel marks and niches.
Understand how the city stored sudden flash floods; the ruins still show the lines of the old water channels.
It was a stop on the spice route, and the columns and stairs behind the valley open far wider than the gorge mouth.
Where the Siq narrows to its tightest, the light suddenly opens and Al-Khazneh stands whole in the cliff. Columns, cornice and the pediment above are all carved from the same block of sandstone, not built up. The façade is peppered with small holes, left by local Bedouin who once fired at the stone, believing treasure was hidden behind it.
The valley can be hit by sudden flash floods, so the water had to be held first. The Nabataeans built dams along the gorge, dug cisterns and laid channels, storing the sudden water for use through the long dry spells. Being able to live here permanently rested on this knack for catching water.
Past the gorge the ground opens out, and a paved avenue, rows of tombs and lines of columns run along the valley. The tomb interiors often hold only a few small niches, while the outer façades are richly carved; the grandest sits on the mountain and needs a long climb to reach.
Don't put it on your arrival or transit day. Stay closer to the canyon mouth the night before, and give the whole day to it.
People settled here as early as 7000 BC, and at Beidha to the north a Neolithic village survived. In the 4th century BC the Nabataeans made a foothold among these rocky hills, and two centuries later made it the capital of their kingdom. They had been nomads following water and pasture, and chose this spot because the cliffs enclosed it tightly and a spring there never ran dry.
Flash floods were another matter. Dams, cisterns and channels dug from the archaeology show they held back the sudden water and stored it, drawing on it through the dry season. Terracotta pipe lines cut into the rock faces and ground carried water from the canyon edges into the city. With steady water, the city could become an oasis in the desert.
With water steady, goods could move. The frankincense route passed through here, and the Nabataeans made the city a regional hub: west to Gaza, north to Damascus, south to the Red Sea, and a desert road to the Persian Gulf. At its peak in the 1st century AD the city held some 20,000 people.
The gorge is the Siq, the narrow slit that is the entrance. At its end, Al-Khazneh stands whole in the cliff: columns, cornice and the pediment above are all carved from the same rock, not built up. What it was for is still debated; one theory links it to the tomb of the Nabataean king Aretas IV.
The façade is peppered with small holes, from local tribes who believed treasure was hidden behind the stone and fired at it. Most tombs follow a Hellenistic style, brought back through the Nabataeans' wide trading; inside they are plain, with only a few small niches cut in the rock.
The largest in the valley is called Deir, dated to the 1st century BC, with inscriptions linking it to King Obodas I. It sits on the mountain and needs a separate uphill walk; its great façade is wedged between jagged peaks, wider even than the one at the gorge mouth.
In AD 106 Rome annexed the Nabataeans and formed the province of Arabia. The city did not fall at once; Trajan built a road through it and Hadrian visited in 130, striking its name on coin. But sea routes gradually took the spice trade, and Palmyra drew the caravans away.
An earthquake in 363 destroyed many houses and damaged the vital water system. In Byzantine times several churches were built, one yielding 140 papyri — mostly 6th-century contracts — showing the city still kept ordinary life then. After the 7th century it almost vanishes from the records.
For a long stretch only a few nomads moved through; until 1812, when the Swiss traveller Burckhardt recorded it again. In 1929 a four-man expedition surveyed it systematically, and later repairs worked mostly from the Siq entrance and drainage; the gorge floor was rebuilt from 1996, and in 2003 a maintenance plan for the drainage system was set.
Walk the stone-paved gorge first and pause at its end, then follow the valley past the columns, and finish by taking one uphill path to the heights.
A good half-day for the gorge, valley and one high tomb; a full day to add the upper trail
After rain the gorge closes sections temporarily; check notices for how far you can go
Gorge floor and trails are loose stone and steps; the climb to Deir is a sustained uphill — split it
The ochre sandstone reads deepest in raking light; midday glare is strong — check the weather first
If you're planning your Jordan days, tell me whether you want one day or two here, and whether your group can manage long uphill climbs.
