Dr. Leen Ritmeyer is an archaeological architect who specializes in Jerusalem and its Temple Mount. He has been involved in numerous excavations and maintains a Blog. He lectures around the world and has been published extensively.
In 2008, Dr. Ritmeyer posted new dating information on some of the stone blocks in the Temple Mount’s eastern wall. I had the privilege today of seeing these stones up close. The video below explains it.
With this dating, these stones have witnessed the Assyrian Sennacharib (2 Kings 19), three assaults by Nebuchadnezzar (2 Kings 24-25), the Return under Zerubbabel (Ezra), the rebuilding of Jerusalem’s wall (Nehemiah), all of the histories with the Greeks and the Maccabees, Herod’s reconstruction, Jesus, and the Roman destruction. This does not include all of the wars and destruction that have occurred here since the 1st century.
You can read Dr. Ritmeyer’s two original posts on the subject here and here.

Very cool!
The link to the video seems to have vanished.
I just checked it and the video works fine on my end. Could it be a browser issue? I’m running Safari on a Mac. In any case, here is the direct YouTube link: http://www.youtube.com/watch?v=y9DJSAdO-pw
Hope it helps!
