Achasanseong, Mountain fortress in Gwangjin District, Seoul, South Korea.
The stone and earth fortress stretches across the summit of Achasan Mountain, featuring defensive walls that extend for more than one kilometer at 200 meters elevation.
Built during the Three Kingdoms period, the fortress changed hands between Baekje, Goguryeo, and Silla, with the Goguryeo general Ondal meeting his death there in battle.
Archaeological excavations at the fortress reveal artifacts from multiple kingdoms, documenting the progression of military architecture and daily life across different periods.
The fortress grounds contain marked walking paths with information panels, connecting visitors to various sections of the fortification and providing views of Seoul.
The fortress walls incorporate architectural elements from three different kingdoms, as each successive ruler modified the defenses according to their military strategies.
