Ssangchungsa is a shrine in Doyang (known also as Nokdong by many) on the southwesternmost point of the peninsula that comprises Goheung County South Korea.

The shrine commemorates and is dedicated to the memories of two Joseon Dynasty era naval officer war heroes.

Ssangchungsa is designated Monument #128[1] The original shrine dedicated to Yi Dae-won was constructed in 1587 on Nokdo Island but was destroyed during the Japanese invasions of Korea (1592–1598).

In 1591, Jeong Un was appointed Captain of Nokdo (the Left Jeolla Navy) and fought against the Japanese under the command of Admiral Yi Sun-sin.

On 10 February 1587 the next year, about 20 vessels of Japanese pirates led by Wokou (alternate spelling: Waegu), guided by a Korean traitor Sa Hwa Dong, conducted a raid on Sonjuk Island (alternate spelling: Sondae) in what is now Goheung County, South Jeolla province.
