About Hajukdo Lighthouse

Also known as: Hajukdo (Hajuk-to)

Hajukdo Lighthouse is a hexagonal white concrete tower standing 6 meters tall, with its light positioned 100 meters above sea level. It emits a white flash every 5 seconds, visible for 24.9 nautical miles. The lighthouse is situated on an island approximately 8 kilometers north of Daeheuksando, marking the northernmost extent of the Heuksan island chain. An earlier navigational aid previously stood on a round tower at this location. The structure is located near the Port of Mokpo in South Korea's South Jeolla region.

Why it matters: This lighthouse is essential for ships approaching or departing the Port of Mokpo, specifically warning them of the northern tip of the Heuksan islands. Its light helps prevent groundings and ensures safe navigation through this island-dotted region.
