The Manboksa Temple site is located on a hillock with Girinsan Mountain on the north and a wide, flat field on the south. It is reported to have been built during the reign of King Munjong (AD 1046~1083) of the Goryeo Period. Records suggest that there have been five-story and two-story main Buddha halls and about 10m-long Buddhist image in there. At that time, it was a big temple having many buildings including Daeungjeon, the main hall of the temple, and hundreds of bonze but was burnt down at the same time as Namwonseong Fortress's fall during the Japanese Invasion of Korea in 1597. At the time of excavation and research, vestiges of many buildings were found, including celadon, white porcelain, and many roof tiles. They provide very important information in studying art history of the Goryeo Period. The present relics remaining in the temple site are the Five-story Stone Pagoda (Treasure No. 30), Stone Pedestal (Treasure No. 31), Flagpole Supports (Treasure No. 32), Stone Standing Buddha (Treasure No. 43), and others. It is one of the representative temples of the Goryeo Period as a temple following the temple arrangement of the Goguryeo Dynasty, carrying immense significance.
