About Geumseong Lighthouse

Also known as: Geumseong (Kumsong)

The Geumseong Lighthouse, built in 1986, stands on a reef off the southern coast of Dolsando, near Yeosu-si in South Korea's South Jeolla region. This octagonal concrete tower, painted red, rises 10 meters high, with its light positioned 9 meters above sea level. It emits a single red flash every six seconds, visible for 10 nautical miles. The lighthouse is accessible only by boat, and while the site is open, the tower is closed to the public. The nearest port is Yeosu, 8.6 kilometers away.

Why it matters: This light warns vessels of the reef it marks, aiding safer navigation along Dolsando's south coast.
