Shangjing (Capital of Balhae) Ruins

The fortress remains of Sanggyong Yongcheonbu, the capital of Balhae, located in present-day Heilongjiang Province, China. Traces of a rigidly grid-planned city modeled after Tang dynasty Chang'an remain, demonstrating the high level of Balhae civilization. The ruins of palace sites, temple sites, and city walls stretch across a vast area. It is a core site conveying the prosperity of Balhae, which was called the 'Flourishing State of the East'.
