Gyeongcheonsa Pagoda (Korean: 경천사십층석탑) is National Treasure of Korea No. 86. It was designated by the South Korean government on December 20, 1962. An inscription on the first story of the pagoda states that it was erected in the fourth year of King Chungmok in 1348. The pagoda was first placed at the now-lost Gyeongcheonsa Temple which sat at the foot of Mt. Buso in Gwangdeok-myeon, Gaepung-gun, Gyeonggi-do Province. During the Japanese occupation of Korea, in 1907 the pagoda was taken to Japan. In 1918, the pagoda was returned and placed on the grounds of Gyeongbokgung Palace. Today, the pagoda stands in one of the main halls of the National Museum of Korea. The pagoda stands 13.5 m in height and is ten storeys tall. However, because of the three-tiered foundation, it is a common mistake to believe that the pagoda has thirteen storeys. Unlike most Goryeo-era pagodas, this pagoda is made from marble. The preferred material of Korean sculptors was generally granite. The later Joseon-era Wongaksa Pagoda is stylistically very similar and is believed to have been heavily influenced by the Gyeongcheonsa Pagoda. Gyeongcheonsa Pagoda sits on a three-tiered foundation which projects in four directions like a cross. The first three storeys of the pagoda share the same shape as the foundation. Each panel of this tiered foundation is carved with Buddhas, Bodhisattvas, flowers, and arabesque patterns. The remaining storeys are square in shape and share intricate detailing which tries to create the illusion that the marble pagoda is made from wood. Each remaining storey has railings, a hip-and-gabled roof, eaves, and carvings made to suggest that each roof is tiled. This pagoda is very valuable because it preserves the Goryeo-era wooden architectural style that has been mostly lost. According to the South Korean Cultural Heritage Administration, this pagoda is one of the finest examples of Korean stone work and is of high artistic value.

Two gold necklaces of the Queen Consort of King Muryeong of Baekje were discovered in a 1971 excavation of their tomb. Designated as the 158th National Treasure of South Korea in 1974, the necklaces are held in the Gongju National Museum. In 2021, the museum commemorated the excavation's fiftieth anniversary by exhibiting more than 5,000 relics from the tomb. The 14cm and 16cm-long necklaces consist of 7 and 9 segments, respectively. The 7-part necklace lay beneath the other in the tomb, indicating that they were worn together. The center is the thickest part, with a slightly curved shape. A hexagonal golden stick narrows into a loop, connecting it with other similar loops. The parts away from the loops are tied, 10-11 times for the smaller one and 6–8 times for the larger.

The bronze brazier with demon face decoration is a Goryeo-period bronze brazier with its demon-shaped body. The jade color is well covered all around, whereas its handle and base plates for the charcoal are not found. In recognition of its unique design, the artifact was designated as the 145th National Treasure of South Korea in 1972. Having been possessed by a private collector, the brazier was donated to the National Museum of Korea in 2006. The cauldron-shaped body is upheld by the supporting three animal-formed legs with its 12.9 cm height. The upper part has curved shapes similar to three peaks of the mountains with 2 loops on each side. Given the facts that ventilated holes were dug at the body of the brazier, it’s also possible to have an assumption the artifact was primarily used for cooking or tea-brewing.

Details as such were not recorded in Annals of Joseon until this decree was verified. Significant features are the mixture of linguistic usage such as the Idu script, printed by wooden movable types and a rare printed document from early Joseon period.
