On the northern cliff-side escarpment of the mouth of Wadi al-Hasa is a cave hewn into the rock with two interconnecting chambers. The cave must have been visible for centuries but it was neither fully investigated nor completely understood. The entire southwestern terrace therefore was constructed in order to support a platform on which lay a church larger than what remains in the eastern hewn-out cave. By the time it was reinvestigated in more detail during a regional survey, numbered and characterised as a hermitage, it had been substantially looted. The hermitage at Wadi al-Hasa may be characterised as a cliff-side memorial site venerating the burial place of two saintly ascetics. The Greek etched inscription naming it a holy place indicates that it was a recognised early Christian pilgrimage site in Byzantine Palestina Tertia, perhaps related to a passage in the Bible.
