About Sanji Lighthouse Sanji Lighthouse locates in the ridge of Sarabong Mountain with a view of Jeju Port at one sight and lights the front gate of Jeju. With its geographical importance, Sarabong Oreum (volcanic mountain peak) has been a defence facility protecting invasion of foreign enemies since Joseon Dynasty. It had the role of military base during Japanese colonial period and in October 1916, 6 years after the Colonization Treaty, the lighthouse was built here. While Sanji Lighthouse was used as a coordinate for vessels sailing north of Jeju, with expansion of Jeju Port for international travel liners and big cargo ships, it is lighting their seaways brightly these days. At first, it launched as an unmanned lighthouse, then it was altered to manned lighthouse in 1917. In December 1999, with construction of the new light tower, it reopened as the present facility. Despite the time difference, the architectural style of the old light tower was considered when building the new light tower and the two match together well. The marine lantern of the 18 meter high new light tower was changed in December 2002 to a huge rotary marine lantern with high light power developed by Korean technologies. The light flashes every 15 seconds and it can even be seen from the distance of 48 kilometers far. The area surrounding the lighthouse is a large marine park and boasts a splendid scenery. It is near from Jeju Airport so that it can be easily reached by bus or taxi. It now became one of the tourist attractions apart from the role of the lighthouse. When the red light of the sun reflects the sea, shapes of fishing vessels can be seen in the dark. The lighthouse opens their way.
