Three excavation trenches, center, in front of the trees, dug by Kathleen Kenyon at the Sukenik-Mayer wall appear as horizontal slashes in the roadside. When Kenyon first dug these trenches, she identified the wall segments exposed in them as belonging to a protective enclosure for Titus’s Roman army camp. Later she changed her mind, deciding that Titus built the wall to surround and trap Jerusalem’s Jewish residents.
