The castle is a classic example of a 'Waeseong,' a style of Japanese fortification characterized by complex, multi-layered defensive walls.
The fort was the site of a major victory for the Korean Admiral Yi Sun-sin and the Ming dynasty general Dong Yiyuan during the 1598 Battle of Sacheon.
The site was constructed using earth and stone excavated directly from the hill to create a secure defensive perimeter.
The location was specifically chosen for its high elevation and proximity to the sea to monitor enemy naval movements in Sacheon Bay.
In 1598, the site was the location of a major military engagement known as the Battle of Sacheon, which resulted in significant losses for the Japanese forces.
After the war, the site was largely abandoned until it was converted into a park in the 20th century.
Sacheon Seonjinriseong, also known as Seonjinri Waeseong, is a Japanese-style castle site built during the Imjin War by the forces of Toyotomi Hideyoshi in 1597. The site features stone ramparts and earthern fortifications strategically positioned on a coastal cliff overlooking the Sacheon Bay.
