About Yeocho Lighthouse

Constructed in 1967, Yeocho Lighthouse stands as a cylindrical concrete tower, 13 meters high, painted black with a red horizontal band. It is mounted on a round concrete pier in a sea region defined by a reef southwest of Yeosu harbor's west entrance. The light emits a single white flash every 5 seconds from a focal height of 15 meters, visible for 11.9 nautical miles. The lighthouse is situated on a reef approximately 5 km southwest of the harbor entrance and a similar distance northwest of Dolsando. The site is open to visitors, but the tower itself is closed.

Why it matters: This lighthouse is critical for the safe passage of ships entering and exiting Yeosu harbor, specifically warning mariners about a reef located southwest of the entrance.
