Ancient City of Changji

　　   The Ancient City of Changji is situated in Changji City and is commonly referred to as the Tang Dynasty City. In the early 1980s, archaeologists from the Archaeological Research Institute of the Xinjiang Academy of Social Sciences carried out on-site surveys. The city is rectangular in shape, approximately 1,000 meters long from north to south and about 600 meters wide from east to west. The city walls were built using rammed earth, with each layer about 6 centimeters thick. In 1964, remnants of the eastern wall still stood at 500 meters and the northern wall at 600 meters. The highest remaining section of the wall reached about 6 meters, with the top of the wall being up to 3 meters wide. The northern wall is largely intact, featuring 15 battlements—eight to the west of the barbican and seven to the east. Each battlement is about 19 meters wide and spaced roughly 30 meters apart. Inside the ancient city, there is a large earthen platform running north-south, standing approximately 5 meters high. This platform was constructed using adobe bricks that measured 20 centimeters in length, width, and 12 centimeters in thickness. However, another four platforms were built by ramming earth, with layers about 8 centimeters thick—consistent with the construction method of the city walls—indicating that these platforms were built during the same period as the city walls. Due to infrastructure construction, two significant historical sites and cultural relics were discovered within the ancient city.
