I should add here that there is some considerable debate as to whether the "wailing wall" is actually part of Herod's Temple (the second temple complex) at all, or actually a wall of the Roman prison that was attached on outside the Temple on the grounds. We know from Josephus that Herod's Temple was razed to the ground with not one stone left on another. That would seem to indicate that the western or wailing wall was not actually any part of the Temple, unless it was part of the sub-foundation.
