Welcome to Jerash
Jerash is the modern name of Gerasa, a city that flourished in the Roman and Byzantine periods and was one of the ten cities of the Decapolis, a league of Greek-speaking cities in the eastern Roman provinces. It was at its height in the 2nd century AD, when it was rebuilt on a grand scale with a paved and colonnaded main street, an oval forum, temples and theatres.
It survives unusually well because of what happened next. Earthquakes and a shift in trade routes left the city in decline, and it was gradually covered by sand and largely abandoned rather than built over. Excavations began in the 1920s and continue, and much of the site has been restored, making it one of the most complete Roman provincial cities in the Middle East.
The modern town of Jerash sits next to the ruins, and the site is a short drive from Amman. It is an easy half-day trip, though a full day lets you see the whole site and the museum at a comfortable pace.
