Where Petra is and what it was
Petra lies in southern Jordan, in a basin ringed by sandstone mountains, a short distance from the modern town of Wadi Musa. It was the main city of the Nabataeans, an Arab people who grew wealthy from caravan trade, including the incense trade of Arabia, and it flourished roughly from the 2nd century BCE to the 1st century CE before passing under Roman and then Byzantine rule. It has been a UNESCO World Heritage Site since 1985.
Petra is not a lost city. Local communities always knew where it was, and Western travellers began describing it in the early 19th century. What most visitors call “Petra” is really two things: the famous rock-cut tombs and temples, and a much larger ordinary city of streets, markets, houses and water works that stood on the valley floor.
The approach and the Siq
The route from the entrance gate leads down a broad path past early tomb monuments, including blocks of rock the Nabataeans left standing and carved. Then it narrows into the Siq, a natural cleft in the rock about 1.2 kilometres long. In places the walls rise high overhead and the passage is only a few metres wide.
The Siq was both the ceremonial entrance and the water-managed gateway to the city. Look for the channels cut into the walls, and for worn carved niches that once held sacred stone blocks. A dam near the entrance was built to divert flash floods away from the passage, a reminder that the Petra water system shaped almost everything about the site. After heavy rain the Siq can still flood, so conditions on the day matter.
The Treasury
The walk ends with a sudden view of the Treasury (Al-Khazneh), a two-storey facade roughly 40 metres tall, cut directly into a cliff face. It is the monument on most postcards, and it is probably a royal tomb rather than a treasury. Its date, its sculpture and the legend of hidden pharaoh’s gold belong to a separate story about the Al-Khazneh Treasury. For planning, the key point is that it sits in a confined space, so it is often busy at midday.
The Street of Facades and the theatre
Past the Treasury the valley opens out. On the right-hand side stands the Street of Facades, a long row of tomb fronts at different heights, many with the stepped, crenellated tops typical of Nabataean work. These smaller monuments show how the same ideas were used for modest tombs as well as royal ones, and how the rock-cut facades were carved from the top of the cliff downwards.
Close by is the theatre, also cut into the rock. It is Nabataean in origin and was later altered in Roman times. Seating is carved in a semicircle facing the main street, and it gives a sense of how public the old city centre was.
The Royal Tombs
Opposite the centre of the valley, high on the cliff of Jabal al-Khubtha, are the Royal Tombs, including the Urn Tomb, the Silk Tomb, the Corinthian Tomb and the Palace Tomb. Their names are modern and do not say who was buried inside. The Silk Tomb takes its name from the bands of colour in its rock, part of the story of the rose-red sandstone that gave the city its nickname. These tombs are best seen in the afternoon light, when the facades are less shaded.
The colonnaded street and the city centre
The valley floor is the part many visitors rush past. The colonnaded street, which runs along the former stream bed, was lined with columns and shops and was rebuilt under Roman rule. Along it stand a gateway marking the sacred precinct, the large Great Temple complex, the freestanding Qasr al-Bint temple and the remains of other buildings. Roman-period street plans like this were common across the region, and the Gerasa colonnaded street, further north in Jordan, makes a useful comparison.
A Byzantine church with mosaic floors stands near the temple area. The papyrus scrolls found there are among the Petra archaeological finds that have changed how the late city is understood.
The Monastery and the high places
The Monastery (Ad Deir) lies up a rock-cut stairway of around 800 steps that begins beyond the city centre. Its facade is broader than the Treasury’s and plainer, with a large central doorway. The name is a later one, and the building was probably a temple or assembly hall rather than a monastery. The climb takes time and is demanding in summer heat, but the open area in front of the monument is a rewarding place to rest. A short extra walk leads to viewpoints over the valley and the wider Wadi Araba.
The High Place of Sacrifice, reached by another staircase, is a mountaintop ritual area with altars and open-air platforms. It offers views over much of the city and is a good way to understand how the basin is laid out.
Beyond the main trail
Several side routes reward those with more time. The Wadi Farasa area has gardens, tombs and a monumental staircase. A few kilometres to the north lies Little Petra (Siq al-Barid), a smaller group of rock-cut dining rooms and houses that was probably a suburb or caravan stop. Both give a calmer experience than the main axis.
Practical notes
- Time: the highlights can be seen in a long day, but two days are more comfortable. The distances are larger than they look on a map.
- Season: spring and autumn are typically more comfortable than midsummer, when shade is scarce. Winter can be cold, and rain brings flood risk.
- What to bring: sturdy shoes, water and sun protection. Surfaces are uneven and many routes involve steps.
- Tickets and rules: entry fees, opening hours and evening events change, so check the current official information before travelling.
- Respect the site: do not climb on monuments or touch carved surfaces. The soft sandstone erodes easily, and the Bedouin community that has long lived in the area depends on the site’s good condition.
Petra rewards slow exploration. Understanding the pattern, with tombs along the approach, a central valley city and temples and high places on the surrounding rock, makes the individual monuments easier to interpret, and the Nabataean society that created them far easier to imagine.
