A Deep Dive into History
The history of Geoje stretches back thousands of years, with Neolithic era artifacts discovered on islands such as Naedo, Sandaldo, and Isudo. While early history is primarily archaeological, written records place Geoje within the Dokro kingdom of the Byeonhan confederacy around 0–300 AD. It later became part of the Gaya confederacy before being absorbed by the Kingdom of Silla.
In 757 AD, the Silla King Gyeongdeok officially classified the area as "Geoje-gun" (Geoje County). Throughout the centuries, the island has held immense strategic importance. In 1419, it served as a naval preparation site for the Gihae Eastern Expedition. Most notably, during the Seven-Year War in 1592, the legendary Admiral Yi Sun-sin secured a massive naval victory against Japanese invaders near Okpo.

During the Korean War (1950–53), Geoje became a significant site for the settlement of 170,000 Prisoners of War (POWs). A 11.8 square kilometer camp was established, which later became a site of historical documentation regarding human rights during the conflict. Today, a portion of this history is preserved as a tourist attraction.
Industrial Powerhouse: The Shipbuilding Hub
In recent decades, Geoje has emerged as a global leader in the shipbuilding industry. This economic engine has provided stability for the region, helping it withstand major market fluctuations like the 1997 Asian market crash. A significant portion of the local population—nearly 33% of workers—is employed in this sector. Major facilities include Samsung Heavy Industries in Gohyeon and Hanwha Ocean in Okpo.
