Where does the Chazan stand for the amidah?

Hi,

The "amud" where the Chazan stands for the amidah should be centered along the wall toward which the shul davens and where the Aron is located, close to the Aron. However, this is not a hard and fast requirement, such that one could not daven in a shul that was arranged differently.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 2:28)

Have a great day,
Mordechai
