Bulguksa Temple was built at the request of Kim Dae-seong in the 10th year of King Gyeongdeok`s reign (751) of Unified Silla. It is the place where the spiritual world of the people of Silla, who wanted to realize the utopia—the Buddhist Elysium where the past, present, and future Buddhas live, is well revealed. According to 『Samguk Yusa』, Kim Dae-seong built Seokguram Grotto for his parents in his previous life and Bulguksa Temple for his parents in his present life. However, he could not finish building it until he died in December of the 10th year of King Hyegong’s rule (774), and after that, it was completed by the Silla Dynasty and used as a temple to pray for the blessing of the country.The Three-story Stone Pagoda of Bulguksa Temple, Gyeongju and Dabotap Pagoda (National Treasure) of Bulguksa Temple, Gyeongju are each built on the east and west sides of the courtyard in front of Daeungjeon Hall, the main temple, and the west pagoda is the three-story stone pagoda. The original name of the pagoda was “Sakyamuni Residing Sermon Pagoda,” and it is called “Seokga Pagoda” or “Seokgatap” for short. The reason why the two pagodas were built at the same location is in accordance with the contents of 『the Sutra of the Lotus』, which says that “the Buddha of the past,” the Dabo Buddha who stands next to Shakyamuni, proves that ‘the Buddha of the present’, Shakyamuni, is right when he preaches the Dharma. Seokgatap (the Three-story Stone Pagoda of Bulguksa Temple, Gyeongju) and Dabotap are the most representative stone pagodas in Korea, and their heights are similar at 10.75m and 10.29m, respectively. The pagoda is presumed to have been built in the 10th year of King Gyeongdeok of Unified Silla (751) when Bulguksa Temple was founded. As it is a stone pagoda with a three-story pagoda body built on a two-tiered stylobate, it is an excellent work of the Unified Silla Dynasty in the 8th century, inheriting the style of the East and West Three-story Stone Pagodas at Gameunsa Temple Site, Gyeongju (National Treasure) and the Three-story Stone Pagoda at Goseonsa Temple Site, Gyeongju (National Treasure).The stylobate of the second floor is firmly woven to support the weight of the entire pagoda, and by using wooden architecture as a model, each corner of the upper and lower stylobates was carved out of stone to create a pillar shape. Such pillars are also engraved on the body of the pagoda, and all the corners of the roof stones are raised, adding to the feeling of flying lightly throughout the pagoda. Unfortunately, in September 1966, the pagoda was damaged by grave robbers, and while repairing the pagoda in December of that year, a square space was discovered on the front of the body stone on the second floor where the sarira of Buddha were enshrined. Various sarira cases and relics were found here, but among them, 『MugujeonggwangDaeDharanigyeong』 (National Treasure), a mantra, is particularly eye-catching. It is the world`s oldest woodblock print and is made of paper mulberry.The pagoda`s headdress (upper part) is presumed to have been lost before the 16th century, but it was restored in 1973 after the headdress of the East and West Three-story Stone Pagodas (treasure) of Silsangsa Temple in Namwon. A lotus flower pattern is engraved on the cornerstone-shaped stones around the pagoda, which is also interpreted as a clean place where the Buddha`s sarira is placed.This pagoda is also called `Muyeongtap` (no shadow tower). There is a sad legend about Asanyeo, who came to Seorabeol, Capital City of Silla in search of Asadal, a stonemason from Baekje who built Seokgatap, and had to throw herself into a pond without even meeting her husband.
