🏺 Jerash Ancient City

Ancient Gerasa — modern Jerash — was a prosperous Decapolis city on the empire's eastern frontier, flourishing from the 1st century BCE through the 7th century CE before an earthquake in 749 CE and the subsequent decline of Byzantine trade routes left it largely abandoned and unplundered. That abandonment is the source of Jerash's extraordinary condition: without the continuous rebuilding that obliterates most ancient cities, Gerasa's urban grid survives in a completeness found nowhere else in the Middle East and matched outside Italy only by Pompeii.

The visitor enters through Hadrian's Arch — built in 129 CE to commemorate the emperor's visit — and proceeds to the Hippodrome, where daily re-enactment shows recreate chariot racing and Roman legionary drills. Beyond lies the city proper, beginning with the extraordinary Oval Plaza (Forum): an elliptical colonnaded space 80 by 50 metres, its flagstones still carrying the wheel ruts of Roman carts and its surrounding 56 ionic columns still standing. The Cardo Maximus (main colonnaded street) runs north from the Forum for over 600 metres, its original paving stones intact beneath the columns that once supported a covered walkway. Side streets lead to the South Theatre (3,000 seats, still used for performances at the annual Jerash Festival), the Temple of Artemis with its enormous standing columns that visibly tremble in strong winds, the Nympheum (monumental fountain house), and the North Theatre (1,600 seats). Byzantine churches from the 5th and 6th centuries pave the eastern district with vivid geometric and figurative mosaics, the finest of which are covered and lit for preservation.

Systematic excavation at Jerash began only in 1925, when a joint British and American team from the British School of Archaeology in Jerusalem and Yale University initiated a coordinated dig across the ancient urban core. Earlier work in the 19th century had been opportunistic — travellers and Ottoman administrators removed portable objects — but the 1925–1934 excavation campaign was the first to approach Gerasa as an intact city requiring stratigraphic documentation rather than treasure hunting.

The German Evangelical Institute for Archaeology of the Holy Land conducted major campaigns from the 1970s onwards, revealing the Byzantine church district on the eastern slope and recovering hundreds of mosaic floor panels. The Department of Antiquities of Jordan has run continuous excavations since 1975, with notable findings including a warehouse district south of the Oval Plaza containing intact amphorae and trade goods, and a Byzantine-period workshop quarter that produced fine glassware for export across the eastern Mediterranean.

Active excavation continues in the northern part of the city, where a second macellum (covered market) and an extensive bathhouse complex — separate from the known Central Baths — were partially uncovered between 2010 and 2019. The hippodrome, excavated intensively between 1982 and 2002, yielded charioteering equipment, animal bones from the animal hunts (venationes), and a sequence of structural modifications that document how the venue was expanded and adapted across three centuries of use. Unlike many sites where excavation has concluded, Jerash is actively being researched, and the northern districts are still yielding new structural complexes beneath the surface.

Most movable finds from Jerash are held in the Jordan Archaeological Museum in Amman's Citadel and in the Jerash Archaeological Museum inside the visitor compound. At the site itself, several categories of material remain in place:

In situ architectural elements: The 56 columns of the Oval Plaza, the standing columns of the Temple of Artemis (the tallest at 13 metres), the tetrakionion (four-column monument) at the junction of the Cardo and South Decumanus, and the decorative friezes of the Nympheum are all original stonework still occupying their Roman positions. The wheeled-traffic grooves in the Forum paving stones — worn to several centimetres depth over centuries of cart use — are among the most viscerally evocative primary evidence anywhere in the Roman world.

Mosaics: The Byzantine church district contains floor mosaics that were reburied after excavation and are now selectively displayed under protective shelters. The most complete preserved example depicts a calendar frieze identifying agricultural seasons with a precision that provides direct evidence of the liturgical and agricultural year as observed in 6th-century Gerasa.

The Hadrianic coin series: Excavations consistently recover bronze sestertii and silver denarii minted for Hadrian's 129–130 CE eastern tour, establishing a precise terminus post quem for the arch, the south tetrapylon, and several building inscriptions. The Jerash Archaeological Museum displays the fullest local collection alongside bilingual Greek-Nabataean inscriptions that document the city's commercial relations with the Nabataean kingdom before the annexation of Arabia in 106 CE.

Jerash opens daily from 8 AM to 6 PM (summer) and 8 AM to 4 PM (winter). The Jordan Cavalry show — a spectacular re-enactment of Roman chariot racing, legionary drills, and gladiatorial combat — runs in the Hippodrome at approximately 11 AM and 2 PM depending on season; confirm current show times at the visitor centre. Optimal visit timing: arrive at opening time (8 AM) for the emptiest conditions and best morning light on the colonnaded street, then exit by noon before tour buses arrive from Petra and Amman. Spring (March–April) brings wildflowers growing between the paving stones of the Cardo Maximus — one of the most photogenic versions of the site.

Entry: JOD 10 per person (approximately $14 USD), including access to all temples, theatres, the oval forum, and Byzantine churches. The Jordan Cavalry show in the Hippodrome costs an additional JOD 8 per person. The Jordan Pass covers Jerash entry (but not the show) along with the Amman Citadel, Roman Theatre, and 40+ other sites. A site guide at Jerash costs approximately $30–60 per group for a 2-hour tour; licensed guides are available at the visitor centre entrance.

• Urban plan reading — a guide reconstructs the lived experience of a Roman provincial city by moving between market, temple, public baths, and forum in the social sequence that actual Gerasans would have followed
• Temple of Artemis trembling columns — the engineering reason why the enormous temple columns visibly flex in the wind without falling is a subtle structural explanation that no signage conveys
• Mosaic identification — Byzantine churches contain figurative and geometric mosaics of exceptional quality; a guide identifies the iconographic programmes and explains how the church's theological concerns shaped the floor designs
• Inscriptions decoded — Greek and Latin inscriptions carved into column bases and pedestals name donors, dedications, and dates that connect the anonymous ruins to specific historical individuals

Wear solid walking shoes — the Cardo Maximus paving is ancient, uneven, and slippery in wet weather. Bring at least two litres of water per person; the site has limited shade and the walking distance is considerable. A sun hat is essential from April through October. The Temple of Artemis columns are the best place on the entire site to demonstrate the trembling effect — hold a piece of paper between a column and the next stone: the column's movement in the breeze becomes visible. The Jordan Cavalry show in the Hippodrome is genuinely spectacular and worth the extra entry fee for visitors who enjoy living history. After Jerash, the nearby Ajloun Castle adds a crusader and Ayyubid dimension to the same day trip and is only 25 minutes further north.
