Excavations at the southern and eastern fringes of Horbat Kosit, west of Baqa el-Gharbiya, uncovered the peripheral area of the site, which was exploited for various industrial uses and for burial. At Horbat Kosit (East) three strata were recorded, the main one (Stratum III) including a Roman-period burial ground. The site of Nahal Hadera (North) yielded 24 rock-cut graves of a type previously assigned to the Essene or the Nabbatean populations. At Horbat Kosit (South), numerous rock-cut installations, cisterns and a tomb were recovered; the finds date from Early Bronze Age I to the Roman period.
