After the Israelis captured the Old City in June 1967, significant attention was given to the development of the Western Wall area. During creation of the large prayer plaza that exists today, the ground level was lowered by about six feet (2 m). Recently when working with the photographs of David Bivin, I came across this photo.
With the distinctive crack in the rock visible behind the young man’s legs, I set about finding a recent photo of the same rock. The photo below shows the crack behind the man’s right hand. In 1964, ground level was located at the position of his left hand.
Note that he is standing on a chair. This is the best illustration I know of that shows the change in plaza level after 1967.
You can see a photo taken by Amihai Mazar that shows a bulldozer clearing the area in the excellent book by Leen Ritmeyer, The Quest: Revealing the Temple Mount in Jerusalem, page 22.
