This is one of the most famous locations on Earth - The Western Wall or The Wailing Wall. It is holiest sight in Judaism.
Construction of the wall is commonly believed to have begun in 19 BCE under Herod the Great! The wall was part of the retaining wall for the second Great Temple.
As a Christian, I found it to be an immensely moving place. I placed my hand on the wall and said a prayer. Standing at the wall, I was in awe and I felt a tremendous sense of peace.
