Currently housed in the National Museum of Korea, this stone pagoda had once stood at the precincts of Gyeongcheonsa, a Buddhist temple of early Goryeo located in Busosan Mountain in Gwangdeok-myeon, Gaepung-gun, Gyeonggi-do. The pagoda was smuggled into Japan when Korea was under Japanese colonial rule in the early 20th century but was returned in 1960 and had been kept since then in Gyeongbokgung Palace until it was moved to its current location. The pagoda consists of a three-tier base in a polygonal shape and a ten-story body whose lowest three stories feature a polygonal shape, with the remaining seven stories having a square shape in plain view. Both the base and the main body are lavishly decorated with elaborately carved Buddha and bodhisattva images and floral motifs. The body stone of each story above the fourth is equipped with a set of railings and is covered with a hip-and-gable roof. There is an inscription on the first-story body stone, revealing that the pagoda was set up in 1348 when Goryeo (918-1392) was under the rule of King Chungmok (r. 1344-1348). The pagoda has been regarded as a fine example of the foreign style of Goryeo pagodas built in the period as it is, in addition to its unique form, made of marble rather than granite as practically the only type of rock used for Korean stone pagodas until then. The pagoda boasts of a beautiful structure with fine proportion and balance as well as elaborately carved ornamentation and roofstones with carefully rendered details including eaves, preserving the distinctive architectural features of the wooden buildings constructed during the late Goryeo. The pagoda is known to have had an influence on the Ten-story Stone Pagoda at Wongaksa Temple Site, Seoul (National Treasure No. 2) built during the Joseon Period. The original form of the pagoda, which had been marred during the process of smuggling, was restored through a ten-year conservation work (1995-2005) performed by the National Research Institute of Cultural Heritage.
