Jungdong Catholic Church is the first Catholic church established in the Gongju area, founded in 1897. The first priest was French missionary Gi-nang, and in 1921, Father Choi Jong-cheol, the fifth parish priest, planned the construction of a new church, which took its current form in 1937. Subsequently, the church completed the auditorium 'Angel's House,' a new rectory, and a convent. In 1997, to commemorate its 100th anniversary, the church building underwent extensive renovation, and in 1998, it was designated a cultural monument of Chungcheongnam-do. Jungdong Church is regarded as a Gothic-style building representing the transition from traditional wooden architecture to modern architecture. The main hall's floor plan is in the shape of a Latin cross, and the exterior is finished with red bricks. A tall bell tower stands above the central entrance, which, along with the doorway and windows, is decorated with pointed arches. Nearby are attractions such as Gukgogae Culture Street and Chungnam History Museum, making it a great spot for a day trip.
Gongsanseong Gwangbokru is a Joseon Dynasty building located at the top center of Gongsanseong in Geumseong-dong, Gongju-si. It was originally the gate of the central military headquarters stationed inside Gongsanseong, but after liberation, it was named Gwangbokru to commemorate liberation. It is a two-story pavilion with a 3-kan front and 2-kan side, open on all sides, with stairs on the left for access. The roof is a hipped-and-gabled style (paljakjibung) shaped like the character for eight when viewed from the side. Positioned in the southeast part of Gongsanseong at the highest peak, 112.4 meters above sea level, it can be reached after some hiking via Imryugak and Yeongdongru. It is accessible via Ungjin-ro and Wangneung-ro, and public transportation includes buses passing Gongju city bus stops. Nearby attractions include the Gongsanseong fortress, Eungaegol History Park, and Sanseong Market.
Myeongguk Samjangbi is a stele located below Gongbukru at Gongsanseong in Gongju, Chungnam. This stele is a memorial monument honoring the achievements of three Ming Dynasty generals and admirals—Admiral Yi Gong, Deputy Commander Im Je, and Guerrilla Commander Nam Bangwi—who defended Gongju from Japanese forces in the fall of 1598 (Seonjo 31), the year following the Jeongyu War. Originally erected on the southern bank of the Geum River in Gongju, it was later moved to Gongsanseong. During the Japanese colonial period, some characters were defaced by the Japanese and the stele was buried in the backyard of the Gongju-eup office. After liberation, it was relocated back here. The monument consists of three steles. The inscription states that “The three Ming generals reached Gongju in the fall of Seonjo 31, the year after Jeongyu, efficiently managing military discipline and sincerely caring for the residents. As a result, the people of Gongju were safe from Japanese threats and were able to resume their livelihoods only after the Imjin War.” Nearby attractions include Gongsanseong, the Tomb of King Muryeong, Songshan-ri Tumuli, Gongju Fortress Market, and Eungaegol History Park.

The stele is made of square-shaped five-colored stone, with width and thickness nearly the same. Recognizing this value, it was designated as a Tangible Cultural Property of Chungcheongnam-do on January 8, 1976.
