This is the westernmost stone pagoda of the three pagodas that stand in the rear garden of Seongjusa Temple. Although it is known that the temple was built during the Unified Silla Period in an area formerly under the rule of Baekje, few other details about the temple have been transmitted to the present. The temple’s buildings are arranged in a unique way, and other stone relics including a stone monument, pedestal, stone-pole, and corner stone have been conserved along with the three pagodas.
The stylobate supporting the pagoda consists of two stories. The extra supporting stone placed under the first story exhibits a new style transmitted to Goryeo. The first-story of the core stone features a pair of lock-shaped hooks engraved with animal faces on its southern side. Each story has corner and interior pillars, while the roof stone has a four-tiered cornice whose eaves turn sharply upwards. While the top missing, the square finial base for holding ornaments is remained.
The width of this pagoda is greater than that of the other two pagodas, giving it a more solemn appearance. Judging by the style of the stylobate and roof stone, it is assumed that the pagoda was built in the late Unified Silla Period.
During renovation work conducted in 1971, a sarira hole containing nothing but dust was discovered inside the pagoda.
