[Seoul=Newsis] Reporter Lee Suji — The National Heritage Administration announced on the 19th that the “Geoje Sujeong Fortress” in Geoje City, Gyeongsangnam-do, has been proposed for designation as a National Cultural Heritage site. The fortress, also known as “Oksan Geumseong,” has an inscription on a large rock outside its western gate, which refers to its original name. Currently, it is recognized as an Oksanseong in Gyeongsangnam-do provincial heritage.
Based on the historical records like “The Records of the Tongjeyong Camp” and “Geoje Gun-eupji,” the official name for the designation proposal is “Geoje Sujeong Fortress.” Located at the summit of Mt. Sujeong (143m above sea level), this circular stone fortress has a perimeter of about 450 meters.
Archaeological investigations have revealed that the current structure includes sections from the Silla, Goryeo, and Joseon periods. The latest restoration took place in 1873, during King Gojong’s reign. Documentation regarding fortress construction in the “Annals of the Joseon Dynasty” ceases after 1871, making this likely the most recent example of such fortifications.
The National Heritage Administration highlights the fortress’s historical significance due to its construction without central government support, solely by the local magistrate Song Hui-seung and the island’s residents, in preparation for foreign invasions. It provides crucial insights into late Joseon fortification methods. Among the structures, the absence of an ondol (traditional heating system) in one suggests it was a specialized building like a warehouse or government office, notable for the extensive use of lime—considered a premium material.
The fortress’s initial construction techniques, dating back to the late 6th or early 7th century, reflect advances in fortification technology, particularly by Silla as they expanded southward. The commanding view from its summit offers not only a strategic military vantage point but also breathtaking landscapes, including the coastline and Hallyeohaesang National Park.
The proposal for designating “Geoje Sujeong Fortress” as a National Cultural Heritage site is pending a 30-day public comment period and subsequent review by the Cultural Heritage Committee.
