During western Han dynasty, Ji'an was governed by Xuantu Commenandery. In 3 AD, the kingdom of
Goguryeo
(Gaogoli) moved its capital to
Gungnae Fortress
in today's Ji'an. Until 427 CE, Ji'an was the capital of Goguryeo, one of the
Three kingdoms of Korea
, and was called
Gungnae Fortress
, for 400 years until the capital's relocation to
Hwando Mountain Fortress
, also in Ji'an, in 209 CE.
The
Capital Cities and Tombs of the Ancient Koguryo Kingdom
, located in Ji'an and
Huanren Manchu Autonomous County
, Liaoning, have been listed as part of a UNESCO
World Heritage Site
. Ji'an is also dubbed as a "Little
