The West Xia Kingdom (1038-1227) was once a power kingdom, which kept a strong military force and maintained its aggressiveness. In 1227, it was conquered by Genghis Khan.
The Western Xia Tombs (Xixia wangling) are heralded by the Chinese as the "Pyramids of China". They are located on the eastern slope of the Helan Mountain Range, 30km from the western suburbs of Yinchuan and just to the south of the Gunzhong Pass. These edifices cover an area measuring 10km from north to south and 4km from east to west, and are a magnificently crumbling sight, by day or night.
