Dwarfed by a 30-foot wall, David Milson, the dig’s surveyor, draws its magnificent stones. Located on the northeast of the smaller tower (A) discovered by Charles Warren in 1867, the wall displays header-and-stretcher construction, a technique also found in the doorposts of Building D. Once an impressive mystery, this tower and its larger mate to the south are now understood as components in a gateway complex opening into the royal quarter of Jerusalem, probably since the time of King Jehoshaphat (867–846 B.C.)
