There are 15 sites along the axis, such as Temple of Heaven and Imperial Palace. Most of them are on the central axis, but the Temple of Heaven and the Altar of Agriculture, the Imperial Ancestral Temple and the Altar of the Land and Grain are not on the central axis. They are close to the east and west sides of the central axis.
