Archaeologists uncovered a third major ancient fort in the northern Sinai Peninsula. The military significance of the Athar region of North Sinai may have pre-dated Ptolemaic-era and Roman-era fortresses already uncovered at the Tel Abu Seifi archaeological site. Alongside the fort, the mission uncovered housing units, the eastern gates of the two known forts, a limestone road, and remnants of industry. The mission uncovered the distinctive design of the eastern gates of the two known forts, helping show the shape of the entrances. The switch from military-first to industry also coincided with the destruction of earlier stone structures at the site.
