During the Fourth Expedition to Tel Lachish in the years 2014-2017 a series of fortifications was uncovered in Area CC, in the center of the northern edge of the mound. In addition to the previously known city walls of Levels I–IV, the expedition discovered a new city wall, built in Level V and dated to the late 10th and the first half of the 9th centuries BCE.
In the framework of the regional project in the Judean Shephelah, which
started in 2007, four sites were investigated: Khirbet Qeiyafa, Khirbet el-Ra‘i,
Socoh, and Lachish. The data for the 10th century is presented here together
with the relevant biblical traditions. The data is analyzed according to an urban
geography model and the gradual development and territorial expansion of the
Kingdom of Judah is suggested.
