Gyeonhweonsanseong Fortress is a mountain fortress built along the summit of the mountain, named after Gyeonhwon who is said to have constructed it. The connection between this fortress and old fortresses in the Sangju area to Gyeonhwon comes from the Samguk Sagi record stating that Gyeonhwon and his father Ajagae were natives of Sangju. Born as a farmer's son, Gyeonhwon served as a general of Silla, then trained troops here. In 892 (Silla Queen Jinseong's 6th year), he rebelled and attacked several Silla fortresses and in 900 (King Hyogong's 4th year) established his capital at Wansanju and founded Later Baekje. The fortress is roughly quadrangular, using natural cliffs where possible, building walls only where necessary, creating harmony between cliffs and walls. At the four corners are curved walls, with the northeast and southeast corners almost fully preserved. It resembles Boeun’s Samnyeonsanseong (Historic Site) in construction style, being a rare and sophisticated Three Kingdoms period mountain fortress. Visitors can take a light 1-hour walk around the fortress, and there is a Songnisan mountain trail connecting to the helicopter landing site and Munjangdae peak along the Baekdudaegan Ridge.

This royal tomb located at 7 Jeungchon-ri, Hamchang-eup, Sangju-si, is said to be the grave of the founder of Goryeong Gaya. Goryeong Gaya was a country established in the Nakdong River basin region of Hamchang, Mungyeong, and Gaeun before the Common Era, mentioned in the 5 Gaya section of the Samguk Yusa and the Goryeong-gun section of the Samguk Sagi. It was one of six Gayas centered around the Nakdong River in 42 CE, with Hamchang-eup in Sangju as its capital. In 1592, during the 25th year of King Seonjo of Joseon, Gyeongsang-do Governor Kim Su and Hamchang Magistrate Lee Guk-pil discovered a tombstone buried in front of the tomb, confirming it as a Gaya royal tomb. In 1712, King Sukjong ordered the preparation of the tombstone and stone artifacts such as stone lamps, and the tomb area has been maintained several times by descendants to this day. In 1971, during Hamchang urban planning, it was designated as a preservation area and as a Gyeongsangbuk-do monument, currently managed by Sangju-si and descendants. An ancestral rite is held annually on October 1 and March 15, the birth date of Gangsaeng.

This is a Donghak temple located in a flat village surrounded by mountains on all sides in a wide basin. The current owner's father, Kim Juhee (1860–1940), established his base here in 1915 and actively worked to propagate Donghak, a native Korean religion, and expand its followers, reportedly building it in 1924. Four buildings—Dongjae, Seojae, Namjae, and Bukjae—are arranged in the four directions, with the storage building located to the back left. The central building, Bukjae, served as the sacred room; the Dongjae, used as the host's quarters, served as the leader's room; the Seojae, the inner quarters, was used equally by male and female followers; and the Namjae, the side quarters, was used by male followers. Originally, all buildings had thatched roofs but were later changed to slate roofs. It is notable as a rare example of a Donghak headquarters building.
