Excavations near the Nahal Sha‘al streambed exposed a massive wall aligned in a roughly north–south direction. The eastern side of the wall is constructed of dressed stones cemented with lime mortar; the western side is irregular. At the base of the wall, a slope was constructed of lime mortar, reaching, at its thickest, up to one meter in width. Based on the scant pottery finds from the mortar fill between the stones, the construction appears to date from the Late Roman period. The wall would appear to have been constructed to prevent erosion of the bank at this particular place.
