About Wolho Lighthouse

This concrete lighthouse, built in 2000, stands 15 meters tall on a round concrete pier. The cylindrical tower, painted green, is situated on a rock off the south side of Hwataedo. Its light, visible for 10.7 nautical miles, emits a green flash every four seconds. Accessible only by boat, the structure serves as a modern navigational aid near Yeosu. The tower itself is closed to the public.

Why it matters: The lighthouse's distinct green flash marks a hazardous rock formation, helping to prevent groundings for vessels navigating the coastal waters south of Hwataedo.
