Once, 2000 years ago the massive Temple complex was surrounded on four sides by feats of engineering called retaining walls. One of them, on the Western side still stands. But most of it has been covered over the past 2,000 years by houses which were built right up against it. This tour takes you under those houses and allows you to see the length of the wall and beyond it, to the bedrock of  Mount Moriah, the holiest place in Jerusalem and therefore, according to some, the holiest place in the world. As you see the visual displays and walk along the wall you will come to understand the Temple’s history and uniqueness in world history. Exit from the tunnel during the daytime is in the Moslem Quarter right at the beginning of the Via Dolorosa. From there you can be escorted back to the outdoor Western Wall complex, or choose to walk through the Old City on your own.
