The ruins at Jerash (6351272; adult/student & child under 15 JD5/2.500; 8am-4pm Oct-Apr, to 7pm May-Sep) are one of Jordan's major attractions and still have the power to evoke the ghosts of Rome. It's one of the best examples in the Middle East of a Roman provincial city, and is remarkably well preserved.
Irbid is a university town and, perhaps as a consequence, is one of the more lively and progressive of Jordan's large towns. In the area around Yarmouk University, south of the city centre, the streets are lined with outdoor restaurants, Internet cafés and pedestrians out strolling, particularly in the late afternoon.
Pella (Taqabat Fahl)
In the midst of the Jordan Valley are the ruins of the ancient city of Pella (Tabaqat Fahl), one of the 10 cities of the Decapolis. Although not as spectacular as Jerash, Pella is far more important to archaeologists because it has revealed evidence of 6000 years of settlement, from the Stone Age through to medieval Islamic ruins.
