Two Judean city walls at an earlier stage of excavation on the western edge of the mound of Lachish. In this picture the two walls are superimposed. The later wall (Level II), destroyed by the Babylonian army in 588/6 B.C., is seen as a row of stones on the top and flank of the sloping left side of the mound; the earlier wall (Levels IV–III), destroyed by the Assyrians in 701 BC., can be seen preserved to a considerable height, with a ladder leaning against it.
