Lighthouses of South Korea: Samsan Islands

For most of its history Korea was an independent kingdom, or at least an autonomous kingdom under Chinese influence. This came to an end in 1910 when Japan annexed all of Korea. At the end of World War II in 1945 the 38° parallel was established as the dividing line between U.S. and Soviet zones of occupation, and in 1948 separate civil administrations were established in the two halves of the country. The Korean War (1950-53) ended in a draw with the armistice line falling close to the prewar 38° line. The Republic of Korea (ROK; 대한민국, Daehan Minguk in Korean), commonly called South Korea, occupies the Korean peninsula south of the armistice line.

The name Korea, used internationally, is a Western version of Goryeo or Koryŏ (고려), the name of a kingdom that unified the country in the tenth century. From 1392 to 1897 the kingdom was known instead as Joseon or Chosŏn (조선). Today South Koreans usually call their country Hanguk (한국, literally "one country") and the official name of the Republic of Korea is Daehan Minguk (대한민국).

South Korea is divided into eight provinces and nine province-level cities. This page is one of three pages covering lighthouses of the municipal city of Yeosu, a major port in southeastern Jeollanam (South Jeolla) province. Yeosu is located in the central part of Korea's south coast. The city occupies the Yeosu peninsula and includes several hundred islands of all sizes, 49 of them inhabited.This page covers lighthouses of the Geomundo archipelago and other islands lying south of Goheung County and southwest of the Yeosu Peninsula in the Korea Strait. These islands are governed as the Samsan Township (Samsan-myeon) of Yeosu City.

In 2000 South Korea adopted a Revised Romanization System to replace systems formerly used in the West. In the Revised System, the word for a lighthouse is deungdae (등대); dan (formerly tan) is a cape, seom (som) or do (to) is an island, am or amseog is a rock, man is a bay, and hang is a harbor. Some place names may be more familiar to Westerners in the spellings of older systems.

Navigational aids in the ROK are regulated by the Ministry of Oceans and Fisheries (MOF). Most of the lights on this page are maintained by the Yeosu Regional Oceans and Fisheries Administration.

Geomundo Lighthouses
Geomundo (formerly called Komundo by Westerners) is a small group of islands in the Korea Strait about 40 km (25 mi) southeast of Wando and 60 km (37.5 mi) northeast of Jeju (Cheju). The two principal islands, Seodo on the west and Dongdo on the east, shelter a magnificent harbor between them. As a result the islands have strategic importance, and the British established a naval station called Port Hamilton on them in the 1880s. Today the islands are a popular tourist destination with the historic light station as a major attraction. The two islands are linked by a cable-stayed bridge completed in 2016. The islands are attached administratively to Yeosu City.
