Established on March 20, 1918, Jumunjin Lighthouse was the first lighthouse in the Gangwon region. The lighthouse is 3 meters in diameter at the base and 10 meters in x_height with white mortar covering the exterior wall. The building shows the early structure of Korean lighthouse architecture, which is a great value in terms of the nation’s architectural history. The light signal blinks at 15-second intervals and can be seen from 37 kilometers away. The original lighthouse was destroyed during the Korean War but was rebuilt in 1951.
