The excavation at Qiryat Ata, Area O, was undertaken in the southern, peripheral zone of the site. Three primary settlement episodes were revealed: Phases 3 and 2 date to EB IB and consist of two buildings and associated surfaces, while Phase 1 dates to EB II and mainly consists of a large fortification wall. These three phases correlate with the three main occupation strata (III–I) that have been identified at the site. The finds in Area O include two large and homogenous pottery assemblages, dating to EB IB and EB II; four cylinder-seal impressions; flints, representing a relatively ‘clean’ EB IB–EB II assemblage, and a few Neolithic tools; and freshwater mussels that might have been brought to the site for food. These finds enlarge the database of the Early Bronze Age ceramic assemblage at Qiryat Ata, and help to better and more accurately define the nature of EB IB and EB II pottery assemblages in northern Israel.
