About Suinyeo Lighthouse

The Suinyeo lighthouse is a cylindrical concrete tower standing 16 meters tall, painted red. It is situated approximately 600 meters offshore from the northern tip of the Taean peninsula in South Korea. This structure emits a single red flash every 5 seconds, visible for 12.2 nautical miles. The lighthouse complex is accessible by boat, though visitors cannot enter the tower itself. Its nearest port is Daesan, located 4.3 kilometers away.

Why it matters: The Suinyeo lighthouse warns vessels of the northernmost point of the Taean peninsula, helping to prevent groundings along the coastline. This light is particularly important for local fishing fleets and smaller commercial vessels operating in the complex coastal environment of South Korea's western shore.
