About Otakseo Lighthouse
This concrete lighthouse, built in 2008, stands 21 meters tall with its focal plane at 17 meters. Its distinctive black tower is accented by a red horizontal band. It emits a single white flash every 5 seconds, visible for 12.4 nautical miles. Located on a reef approximately 16 kilometers northwest of Nokdo, it lies within the South Chungcheong region. The site is accessible by boat, though the tower itself is closed to the public. The nearest port is Boryeong, 12 kilometers away.
Why it matters: This lighthouse marks a hazardous reef northwest of Nokdo, ensuring safer passage for vessels. A newer, taller tower was described in February 2024, indicating its ongoing importance for regional maritime safety.
