The ruins of Niya (simplified Chinese:尼雅遗址; traditional Chinese:尼雅遺址; pinyin:Níyǎ Yízhǐ), is an archaeological site located about 115km (71mi) north of modern Minfeng Town (also called Niya) on the southern edge of the Tarim Basin in modern-day Xinjiang, China. The ancient site was known in its native language as Caḍ́ota, and in Chinese during the Han Dynasty as Jingjue (Chinese:精絕; pinyin:Jīngjué). Numerous ancient archaeological artifacts have been uncovered at the site.
In Hanshu, an independent oasis state called Jingjue, generally thought to be Niya, is mentioned:
Niya became part of Loulan Kingdom by the third century. Towards the end of the fourth century it was under Chinese suzerainty, later it was conquered by Tibet.
