Jeongnimsa, Buddhist temple ruins in Buyeo, South Korea

Jeongnimsa is a Baekje-era temple site in Buyeo, with a one-pagoda layout: gate, five-story stone pagoda, main hall and lecture hall aligned south to north inside corridors. The corridors form a trapezoid, wider at the north. A Goryeo stone seated Buddha stands where the lecture hall was, and a pond lies before the gate.

Jeongnimsa was the central temple of Sabi, the Baekje capital from 538 to 660. It was destroyed when Baekje fell in 660, then rebuilt in the Goryeo period, as a roof tile inscribed "Taepyeong 8th year, Wujin, Jeongnimsa Daejangdangcho" (1028) shows. In 660 the Tang commander Su Dingfang had the inscription "Great Tang Conquers Baekje" carved on the first story of the five-story pagoda.

The name Jeongnimsa is documented on a roof tile found at the lecture hall site, inscribed "Taepyeong 8th year, Wujin, Jeongnimsa Daejangdangcho", showing the temple was still called by this name in 1028 under Goryeo. The stone pagoda's first storey carries the Tang inscription "Da Tang ping Baekje guo beiming", carved after 660 on the order of Tang commander Su Dingfang, once nicknamed "Pyeongje-tap".

The site lies in Dongnam-ri, Buyeo-eup, with the entrance, middle gate, pagoda, main hall and lecture hall aligned south to north; the corridor enclosure is trapezoidal, wider at the north. A pond excavated in front of the middle gate has been restored, and a shelter built in 1993 protects the seated Buddha. The Jeongnimsa Temple Site Museum on the grounds holds finds such as Baekje inkstones, roof tiles and clay Buddha figures.

In 660, after Baekje fell, Tang commander Su Dingfang had the inscription "Great Tang Conquers Baekje" carved onto the pagoda's first story, starting on the south face and running clockwise, with a seal-script title and regular-script body. The text is now worn, and rubbings are held at the National Museum of Korea.
