Direction of Davening at the Kotel

Q: Should one turn slightly to the left when davening at the Kotel to face the spot of the Temple?
A: There is no need since we do not know the exact spot of the Temple. We therefore face forward. I once asked Rav Simchah Ha-Cohain Kook – who grew up in Jerusalem -- when he was visiting the yeshiva, and he said that the custom is not to turn left (See Rav Aviner's book "Le-Mikdashech Tuv" p. 241 for a short responsum on this question).
