History & Heritage

Formed 5,000 years ago by violent hydrovolcanic eruptions beneath a shallow seabed, Seongsan Ilchulbong rises 182 meters with a dramatic bowl-shaped crater ringed by 99 jagged basalt spires. At its base, traditional Haenyeo women free-divers demonstrate centuries-old sustainable harvesting.

Geologists worldwide consider it the textbook example of a Surtseyan tuff cone, where rising magma interacted violently with seawater to build cohesive ash layers resistant to ocean erosion.

Originally an isolated offshore island, it gradually joined the Jeju mainland through wave-driven sand deposition forming a natural coastal tombolo.
