About this place
Achasanseong Fortress stands on Mount Achasan, 285m above sea level, north of the Han River in Gwangjang-dong, Gwangjin-gu. Baekje built this large fortress to repel Goguryeo while its capital was at Hanam Wiryeseong. After Goguryeo’s King Jangsu captured Baekje’s royal fortress south of the lower Han River, he brought the captive King Gaero here and killed him. When Silla controlled the lower Han, the fortress also became an advance base for attacks on Goguryeo. It is said that Goguryeo’s General Ondal, fighting to stop Silla’s ambitions, died here after being struck by a Silla arrow. The sad love story of Princess Pyeonggang, who traveled a thousand ri to recover her beloved husband’s body, has echoed along the Han River for over a thousand years. The 1st and 2nd excavations identified Goguryeo walls, building sites and a pond site. Excavations beginning in 2015 found numerous Three Kingdoms artifacts, including Silla drainage facilities and Goguryeo pottery. Along a 90m outer section of the southern wall, investigators found characteristic Silla reinforcement structures and 3 drainage outlets; the inner wall contained 2 inlets. At the lookout post site, they identified inner and outer walls, projecting bastions and square platform structures. ✨AI
