THE LEANING TOWER. As a result of earlier excavations in the area next to the Northern Tower, its structural integrity was severely weakened. When this was exposed in the new excavations, it became necessary to dismantle the 9-foot-high tower so it could be properly restored. During this process it became clear that the tower and its adjoining walls were built directly into and on top of the massive stone foundations of the Large Stone Structure (David’s palace; visible at right in the foreground) and the Stepped Stone Structure (visible at left in the background).
