Bronze Age and Iron Age Qubur Bani Isra'in are very large Bronze-Age stone structures, which rise from a rocky plateau overlooking Wadi Qelt.
Hellenistic and Roman periods Several aqueducts have been found along the stream, the oldest dating to the
Hasmonean period (2nd century BCE).
The winter palaces of Hasmonean kings and
Herod the Great stood at the lower end of the valley, where it reaches the Plain of Jericho. A structure within the Hasmonean royal winter palaces, identified by its excavator,
Ehud Netzer, as a synagogue, is now known as the
Wadi Qelt Synagogue, is believed to be one of the oldest synagogues in the world-- although its identification as a synagogue is contested by many scholars. During the
First Jewish war with Rome, insurgent leader
Simon bar Giora is said to have held out in caves in this valley, known formerly as the Pharan brook.
Late Roman and Byzantine monasticism Wadi Qelt (understood as the entire course of the stream, not just the lower course actually called Wadi Qelt by Arabs) contains monasteries and other old Christian locations. an area known to the
Greek Orthodox as Pharan Valley. The
Monastery of Saint George was founded by
John of Thebes around 480 AD, and it became an important spiritual centre in the sixth century under Saint
George of Choziba. Hermits living in caves in nearby cliffs would meet in the monastery for a weekly mass and communal meal. Another Byzantine monastery was excavated at the site known in Arabic as
Khan Saliba. Archaeologists found fine Byzantine mosaics at the former pilgrimage site.
1948 Towards the end of the
1948 Palestine war and from the outset of the
Arab-Israeli war that followed, the springs of Wadi Qelt, which supplied much of the water for Jericho were a primary target for Israel's
biological warfare programme, designed, by contaminating waters with typhus and diphtheria bacteria, to block the advance of the
Arab Legion into the area which, in the
United Nations Partition Plan for Palestine, had been destined for the Arab population. Some evidence suggests that a well-poisoning operation may have unfolded in this area in July of that year.
1967 and after The area was occupied by
Israel in
1967. On December 20, 1968, Israeli lieutenant-Colonel
Zvi Ofer, commander of the elite Haruv unit, former Military Governor of
Nablus and recipient of the Israeli medal of valour, was killed in action in Wadi Qelt while pursuing Arab militants who had crossed the Jordan. ==Tourism==
