The synagogue, or if it is a multi-purpose building, prayer sanctuaries within the synagogue, are typically designed to have their congregation face towards Jerusalem. Thus sanctuaries in the Western world generally have their congregation face east, while those east of Israel have their congregation face west. Congregations of sanctuaries in Israel face towards Jerusalem. But this orientation need not be exact, and occasionally synagogues face other directions for structural reasons, in which case the community may face Jerusalem when standing for prayers.
