About Sinon Hang Lighthouse

Also known as: Sinon Hang (Gakssiseo, Amma Do)

This concrete lighthouse, standing 14 meters tall with a focal height of 13 meters, guides vessels with a green light that flashes once every 6 seconds. Its green, cylindrical concrete tower is mounted on a round concrete pier. The structure is situated on a reef off the entrance to the channel between Anmyeondo and the mainland. Located in the South Chungcheong region of South Korea, it is 13.5 kilometers from the nearest port of Boryeong. The site is open to visitors, but the tower itself is closed.

Why it matters: The lighthouse's green flash warns mariners of a reef at the channel entrance, facilitating safe passage through this intricate coastal area.
