Grounds of the Belian Museum
Erected in 781 AD, the stele gives a brief description of the introduction of Nestorian Christianity into China in the 8th Century.

At the top of stele is a Nestorian Cross; beneath the cross is the heading “Memorial of the Propagation in China of the Luminous Religion from Daqin”. Beneath the heading—not really visible in the photo—is
The History Itself in 1,756 Chinese characters plus a few lines in the Syriac language.
Christianity, along with Islam, was one of the many imports that trodded eastward on the Silk Road. For more on this see the wonderfully informative
Religions of the Silk Road. Also see
The Great Mosque in Xian.
Of course there is much else in the Belian Museum, including many swoon-inducing Buddhist art works. Here are just two samples:

A Tang Dynasty Buddha
A Tang Dynasty rendering of Avalokitesvara, the Bodhisattva of Compassion, unearthed in Xian in 1952.
