About Soyu Lighthouse

Established in 1989, the Soyu Lighthouse is a round cylindrical concrete tower standing 10 meters tall. It is painted black with a single yellow horizontal band. The structure is mounted on a round concrete pier rising from a shoal just off the central east coast of Geumodo. Its light emits one white flash every 10 seconds, visible for 11.3 nautical miles. The site is accessible by boat, though the tower itself is closed to the public.

Why it matters: The Soyu Lighthouse warns of a shoal off Geumodo, preventing groundings and ensuring safer passage for local shipping and fishing vessels.
