Shimao


Shimao is a Neolithic site in Shenmu County, Shaanxi, China. The site is located in the northern part of the Loess Plateau, on the southern edge of the Ordos Desert. It is dated to around 2000 BC, near the end of the Longshan period, and is the largest known walled site of that period in China, at 400 ha.
The city was surrounded by inner and outer stone walls, in contrast to the rammed earth walls typical of Longshan sites in the Central Plain and Shandong. The walls were 2.5 meters thick on average, with perimeters of approximately 4200 m and 5700 m respectively, and feature gates, turrets and watch towers. The earliest site, the "palace centre", was a large stepped pyramid based on a loess hill which had been reworked to make 11 platforms. Each of these was reinforced by stone buttresses. At the top of this pyramid palaces of rammed earth were built. The inner city contained a stone-walled platform, interpreted as a palatial complex, and densely packed residential zones, cemeteries and craft workshops. Unusual features include jade embedded in the city walls, possibly to provide spiritual protection, and paintings of geometrical patterns on the inner walls. Many human skulls were found under the city gate, suggesting ritual sacrifices during construction.
Developments such as bronze working, wheat, barley, sheep, goats and cattle seem to appear here earlier than elsewhere in China, showing that its inhabitants were communicating with Western Eurasian people across extensive trade networks.
