History and archaeology
Scholar Li Zhengyu has identified the Ta'er Temple with the King Ashoka Temple recorded in historical documents. The King Ashoka Temple is described as being located east of Guazhou City, which matches Ta'er Temple's location. It was first built in the Northern Zhou dynasty at the latest, destroyed in Emperor Wu of Northern Zhou's suppression of Buddhism, and rebuilt in the Tang and Western Xia dynasties. In cave 16 of the Yulin Caves, a Western Xia monk named Huicong from the King Ashoka Temple left inscriptions recording his pilgrimage to the cave temple with his disciples. In 627, Tang dynasty monk Xuanzang preached in Guazhou for over a month before he set out for his famous pilgrimage to India, and the Ta'er Temple is thought to be the probable location of his sojourn. The Qing dynasty publication New Gazetteer of Suzhou records the discovery of a broken stone stele in the temple ruins. The remnants of the stele inscription, written in Tang dynasty calligraphy, lauded the 9th-century general Zhang Yichao, who recovered the Dunhuang region after decades of Tibetan control and was awarded high positions by the Tang court. The obverse side of the stele appeared to praise the deeds of Cao Yijin, a tenth-century governor of the Guiyi Circuit. According to local eyewitnesses, a band of Russians came to the site in the 1940s and broke open the main pagoda. They found numerous sutras and paintings inside and took them away. Archaeologists later discovered a paper document from inside one of the smaller pagodas. On it are the printed words of the Buddhist mantraOm mani padme hum, in the Tangut script of the Western Xia. In 2014, Suoyang City and its associated ruins were inscribed on UNESCO's list ofWorld Heritage Sites as part of.
