Hwando, Archaeological site and UNESCO World Heritage location in Jilin, China

Hwando is a mountain fortress 2.5 km west of Ji'an in Jilin, China, built to protect the Goguryeo capital Gungnae. Its walls follow the ridge, enclosing an irregular quadrilateral 6,395 metres around, with the highest point at 676 metres. The south gate opens through a barbican, and two springs inside the walls once supplied the garrison.

In 3 CE King Yuri moved the Goguryeo capital to Gungnae and built the Wina Rock fortress on the mountain. In 198 King Sansang enlarged it and renamed it Hwando, making it the capital in 209. Wei sacked it in 244 and the Xianbei Murong clan burned it in 341.

The name Hwando replaced the earlier Wina Rock fortress name under King Sansang, after he enlarged the mountain stronghold in 198. The fortress worked with Gungnae on the plain below as a paired royal capital, the mountain city guarding the river city. Visitors today see the remains of that pairing in the walls and the south valley gate.

The walls follow a ridge 2.5 km west of Ji'an, with the north side highest and the south gate lowest. Two springs inside the fortress meet near the south gate and drain through a culvert under the barbican. The palace terrace on the eastern slope measures 96.5 m north-south by 80 m east-west.

The fortress walls run 6,395 metres around a layout that is high in the north and low in the south, with cliffs outside the east, west and north ramparts and gentler slopes within. Two springs rise inside the walls, one at the northwest corner and one at the foot of the eastern hill, joining near the south gate before draining through a culvert under the barbican into the Tonggou River.
