In excavations led by S. Bar in 2010-2014 on the western slopes of the small mound (Area D), a large public structure from the early 8th century BCE (Iron Age IIB) came to light. The fortified tower abutted by a storehouse was interpreted as being part of a regional administrative centre, due to similarities with other contemporary public complexes. However, Tel 'Esur is unique in being the only small, countryside settlement, rather than large royal Iron Age estate or city, such as Hazor or Megiddo, where the state or king built an administrative centre. The architectural complex shows enough sophistication to vouch for it being a royal or state-run project, in spite of its size of less than 0.5 ha, which would otherwise be characteristic of a hamlet or farmstead. It comes in the context of both Israel and Judah having many, primarily rural settlements established in the 9th–8th centuries BCE. The excavation director speculates that the Tel 'Esur compound was established during the reign of the Omride king Jeroboam II (786–746 BCE), as part of the measures taken by the kings of Israel to strengthen their grip over the northern valleys and the Shephelah at a time of maximal expansion (see ). The Tel 'Esur complex is the first official presence along the Wadi Ara pass, proof for the interest of the kings of the northern kingdom in this thoroughfare.
