After these stands the main temple complex. This is a walled area within which the ceremonies for worshiping the emperor were carried out. The tomb mound and underground palace stand in a semi-circular walled area north of the temple area. The temple walls are high, with a walkway set on top of them. Each corner is marked with a small tower and two larger towers stand over the north and south gates of the temple area. Within the temple complex's walls stand five buildings. The first four, set on either side of the central axis, were used for preparing the ceremony.
