ABSTRACT Umm Tawabin (‘Mother of Bread Ovens’ in Arabic) is a large fortress overlooking the Wadi ‘Arabah and southern Dead Sea in Jordan. From the time of its discovery by a Palestine Exploration Fund (PEF) expedition in the late 19th century, Umm Tawabin had not been excavated, nor published extensively in spite of its strategically elevated location with panoramic views on all sides, its monumental fortification and numerous and varied archaeological remains until the Ghor as-Safi Project survey (Ariotti 2017) and excavations (Ariotti 2022; 2021; Politis and Ariotti 2020). The goal of this investigation was to determine the extent, function (or multiple functions) and dating of the site, along with the subsistence practices and diet of its inhabitants based on its topographical, architectural and excavated material culture, botanical and faunal remains (Ariotti 2021, Edwell 2023, Hansen and Heinrich, in press). This paper presents an overview of the chronological development and strategic importance of Umm Tawabin from the Hellenistic to Roman periods in view of its stratigraphic evidence, radiocarbon dates and pottery. It also presents some fragmentary remains dated to the Iron Age II.
