Wadi Orjan is known far beyond the area of Al Ayoun (meaning springs) for the quality of its fruit: fig, pomegranate, carob, cherry, plum, and almond all grow here, watered by the spring that emerges from the limestone at the head of the valley. An ingenious system of canals irrigating the orchards has been in place for centuries. The channels and aqueducts were also used to provide hydraulic power to seven mills along the wadi. Some of their remains can still be seen today.

From the few columns, stretches of stone pavement, and other remains which are visible in Pella today, it is hard to imagine the historical importance of this site or its once immense size. Pella has been inhabited for over 10,000 years, though, consistently from the Neolithic Period to the Ottoman rule of the area in the late 1800s.
