Excavations at Khirbat el-Thahiriya exposed a complex consisting of a large building, with an oil press to its northeast and an irrigation system to its west; a refuse heap; and a plastered surface. Also found were a quarry and a juglet dating to Early Bronze Age IB, not related to the other finds. The building (c. 1500 sq m) was partially exposed and three phases were identified, dating to the Byzantine (fifth–mid-seventh centuries CE; Phase 1), Umayyad (650–750 CE; Phase 2) and Abbasid (750–tenth century CE; Phase 3) periods. The three phases of the building were dated by pottery, metal finds, glassware and coins. The building appears to have originally been a monastery that was converted into a farmhouse following the Arab conquest.
