Helan Mountains
Baisigou Square Pagoda (Chinese ) was a brick pagoda in Helan County, Ningxia, China, built during the early years of the Western Xia dynasty (1038–1227), "circa" 1075–1076. It is situated in an isolated location about 10 km into the Baisigou Valley on the eastern side of the Helan Mountains, northwest of Yinchuan, but may have been the site of an important Buddhist temple during the Western Xia. The pagoda was illegally destroyed in 1990; archaeological investigation of the ruins has uncovered a large number of Tangut artefacts and Buddhist relics, including books and manuscripts written in the Tangut language and script.
