Gongju Gongsanseong Fortress [UNESCO World Heritage] (공주 공산성 [유네스코 세계문화유산])

Gongsanseong Fortress is a fortification situated at the heart of Gongju, which served as the capital of the ancient Baekje kingdom (18 BCE - 660 CE) from 475 to 538. Even after Baekje's fall, subsequent dynasties such as Silla (57 BCE - 935 CE), Goryeo (918-1392), and Joseon (1392-1897) continued to use Gongju as a regional administrative center. As a result, numerous historical sites have accumulated in the area over time. From the fortress, visitors can enjoy a panoramic view of Gongju’s city center and the Geumgang River.
