005- Roman Period
Jerash dates back to over 6,500 years ago. It is the site of prehistoric human settlements and was inhabited by early Arabs in the 1st millennium BCE, by Greeks around the 2nd century BCE, and then taken over by the Romans in the 1st century BCE. Known by the Romans as Gerasa, it became one of the great cities of the Decapolis. Today, it is one of the largest and best-preserved Roman cities outside Italy. Within its walls are structures from later periods, including at least 15 Byzantine churches, two Islamic mosques, and Umayyad houses.
A devastating earthquake reduced the city to a small village in 747 CE. Ancient structures remained buried until they were rediscovered in 1806. Half of the Roman city is still buried under modern Jerash.
