> Okay, so what's the Western Wall in Jerusalem for? It's a retaining wall, it's a barrier holding back earth, supporting the man-made Temple Hill next to it. There used to be a Jewish temple there, and this wall kept the temple stable. That's why people pray there today, there used to be a temple. The wall itself was never meant to be a religious site.
