Taewang-neung Pyramid

41.1417°N, 126.1917°E.

The Taewang-neung (Stele of King Gwanggaeto) and tomb mound at Ji'an, Jilin Province, China, attributed to King Gwanggaeto the Great of Goguryeo, who reigned from 391 to 413 CE and whose reign expanded Goguryeo territory by hundreds of kilometres in every direction. The tomb mound is a stepped stone pyramid approximately 30 metres per side at the base and 14 metres tall, of similar construction to the nearby Tomb of the General — built of receding tiers of dressed granite blocks. The associated stele, erected by King Jangsu in 414 CE the year after his father's death, is the largest standing royal inscription of the Three Kingdoms period: a single block of granite 6.39 metres tall and 1.5 metres wide, with 1,802 surviving Chinese characters across all four faces recording Gwanggaeto's military campaigns, the founding myth of the Goguryeo dynasty, and tomb-protection regulations. The stele is the single most important written source for Goguryeo history surviving from the period itself.

A stone pyramid for the king whose conquests defined the maximal extent of Goguryeo, with the empire's autobiography carved on the granite stele in the courtyard.
