About Udo Lighthouse
The Udo Lighthouse is a 7.5-meter cylindrical concrete tower painted white, first lit in 1906. Its focal height reaches 140 meters, providing a geographic range of 28.8 nautical miles. The light emits a white flash every 20 seconds. Situated on the southern tip of Udo island, it was constructed with an automated, acetylene-powered light source from its beginning, negating the need for a keeper's dwelling. Although inactive since 2003, the lighthouse site is open to visitors, offering views of the surrounding coastal area. The nearest port, Seongsan-po, is 1.9 kilometers away.
Why it matters: Its construction featuring an automated, acetylene-powered light from the outset represents an early adoption of technological advancement in lighthouse operation.
