Zhongdutai Site

　　Located in Zhongdutai Village of this county, the site was discovered during the 1981 cultural relics survey. It lies near the northern bank of the Han River, facing the present-day Ankang city across the river. Stretching from the staff residential area of the Ankang Railway Branch in the east to the northern end of the Han River Bridge in the west, the site extends over 2,000 meters in length. Near the site, at Weijiatai and Koujiagou, there are two Han Dynasty pottery kiln sites, along with artifacts such as cloud-patterned eaves tile molds, eaves tiles, slag, and more.

　　When the Ankang Railway Branch carried out earth excavation for infrastructure within the site, it was found that the cultural layer is about 2 meters thick. The upper layer contains relics from the Warring States, Qin, and Han periods, mainly including several types of bronze coins such as "Ban Liang," "Wu Zhu," and "Huo Quan," as well as bronze horse spurs and bronze arrowheads. Pottery items include roof tiles and eaves tiles with rope or basket patterns, square grid-patterned pottery fragments, and pottery pipes, along with the foundations of buildings paved with neatly laid geometric-patterned large square bricks. The lower layer is a Neolithic cultural stratum, with main artifacts consisting of pottery files, pottery adzes, pottery basins, stone axes, stone adzes, stone grinding rods, and tubular bone tools. In 1984, during construction by the Ankang Railway Branch, a Western Han Dynasty currency hoard was discovered at a depth of 0.80 meters below the surface, unearthing over 170 kilograms of "Huo Quan" round coins, which are now stored in the Ankang Regional Museum.

　　The location of the site corresponds with historical records regarding the site of the old Xicheng County. The Commentary on the Water Classic states, “The Han River flows past Yuechuan Mouth and then continues east, passing the south of the old Xicheng city.” It is suspected to be the former site of the Xicheng County seat.
