The Western Wall is the only remnant of the Jewish Temple that was destroyed centuries ago in 70 A.D. by the Romans.
We cleared strict security before entering the compound. Men and women have their own separate areas of the Wall, and a yarmulke or a head covering must be worn. You join a line behind a person who has a place on the Wall, until they are finished. Then it’s your turn to approach the Wall and offer prayer. It’s important to never turn your back on the Wall, and when finished you slowly walk away from the Wall backwards. This is symbolic for not turning your back on God. As I stood waiting, the sight and sound of people gently touching the Wall, wailing, and handing their problems over to God, was extremely personal and I almost felt like an intruder.
I suggest writing your prayer on a piece of paper to insert into the wall before you visit Jerusalem, if you choose. Modest dress is a requirement, and wear a scarf to cover your head as a sign of respect.
