The Western Wall, the most important place to Jews, is nothing more than the remains of the outer wall of the temple (the top where the Dome on the Rock, was where the main temple once stood). What is interesting to note is that during the time of Herod, he was hated by most of the Jews living in Judea, as he over taxed them, and was though of as the tail of the dog. The dog being Rome. What he was interested in was building grand projects through out Israel, and his wall is part of this building project. So after 2000 years, the man who was hated by his people, even by the famous writer Josephus, is now in a way the man responsible for connecting Jews to the Temple and to G-d.
