Kkaejinyeo Lighthouse

Fl Green 4s🇰🇷Gunsan-si, KROperational

Also known as: Kkaejinyeo (Jangjado Northwest)

A round, cylindrical concrete tower painted green, standing 15 meters tall, marks a reef off Jangjado Island. This structure, featuring a double gallery, emits a green flash every 4 seconds from a focal height of 14 meters. Its operational status provides a geographic range of 11.6 nautical miles. The lighthouse is situated off the harbor of Jangjado, an island to the west of Namdo. While the site can be accessed by boat, the tower itself remains closed to the public. Its nearest port is Gunsan, located 13.5 kilometers away.

Why it matters: This lighthouse is essential for vessels entering and exiting the harbor of Jangjado, as its green flash specifically indicates a reef, preventing groundings and ensuring safe transit for local fishing boats and other maritime traffic. The double gallery on its tower is a notable architectural feature.
