Al-Khadra
Al-Khadra lies in the hills near the Chelif valley of northern Algeria, in a landscape of cultivated ground and ancient settlement. The Roman town of Oppidum Novum stood in this part of the valley, and medieval accounts describe gardens watered by the river in the surrounding country. Between the Mediterranean ranges and the Ouarsenis uplands, the Chelif formed a natural corridor through the central Maghreb, linking its settlements along the course of the river.
