On a hilltop opposite the Israelite settlement of Atar Haro’a, in Israel’s central Negev desert, stand the excavated remains of a small square fortress. The author originally proposed that this fortress, like nearly 40 others in the central Negev, was built by King Solomon in the tenth century B.C., but new evidence supports redating this fortress and two others nearby to the Persian period, sixth to fourth centuries B.C.
