Does the wailing wall have any significance to Christianity?

Answer 1

The wailing wall holds significance as being the only known remnant of the Temple of Jerusalem which is accessible to non-Muslims. Because Christianity is also an offshoot of the ancient Judean religion, the wall may hold some religious significance to some Christians. Jesus was know to had visited this temple.

Answer 2

Judaism. The Western Wall or Wailing Wall is the most accessible remaining piece of the Temple in Jerusalem that was destroyed by the Romans in the year 70. It isn't the Temple itself, but just the retaining wall that held up that side of the terrace around the Temple. Still, huge portions of the Jewish liturgy are focused on the Temple. Jews are supposed to face the Temple when praying, the daily prayer services in the liturgy serve to recall the sacrificial services in the Temple, and the Hebrew scriptures is, in large part, a history of the Temple. There is much more to Judaism than the memory of the Temple, but much of the rest is layered on top of that memory.
