The Nestorian Stele (also known as the Nestorian Stone, Nestorian Monument, or Nestorian Tablet) is a Tang Chinese stele erected in 781 that documents 150 years of history of early Christianity in China. It is a 279-cm tall limestone block with text in both Chinese and Syriac, describing the existence of Christian communities in several cities in northern China. It reveals that the initial Nestorian Christian church had met recognition by the Tang Emperor Taizong, due to efforts of the Christian missionary Alopen (Chinese: 阿罗本 pinyin: Āluóběn) in 635. Buried in 845, probably during religious suppression, the stele was not rediscovered until 1625.
