Jeondeungsa, Buddhist temple in Ganghwa Island, South Korea

Jeondeungsa is a Buddhist temple on Ganghwa Island with multiple worship buildings arranged around a central courtyard and surrounded by fortress walls. The grounds contain several halls dedicated to meditation, prayer, and the preservation of important religious texts and objects.

Founded in 381 by the monk Ado during the Goguryeo period, the temple was first called Jinjongsa. It was rebuilt in 1266 and renamed Jeondeungsa in 1282 after Queen Jeonghwa, wife of King Chungnyeol, donated to it; the name means "transmitting the lamp of the Dharma." Burned down, it was rebuilt in 1621, and in 1660 the Jeongjoksan Sago archive for the Joseon Dynasty Annals was installed within its grounds.

The name Jeondeungsa, meaning "transmitting the lamp of the Dharma," was given in 1282 after Queen Jeonghwa offered gifts to the temple. The grounds hold a copy of the Joseon Dynasty Annals, kept in the Jeongjoksan archive built in 1660. Templestay programs let visitors join Buddhist practice.

Visitors can join multi-day temple stay programs that include meditation sessions, traditional Korean meals, and overnight stays in simple rooms. The site is easiest to navigate during quieter weekday mornings when fewer people are present.

The temple bell is a Northern Song bronze cast in 1097, 1.64 m tall with a 1 m mouth, listed as Treasure 393, not a National Treasure. It has no body beyond a pair of crouching dragons forming the loop on top. It came from Sungmyeongsa on Baiyan Mountain in Henan and was taken by Japanese forces during the colonial metal collections; the bell found after liberation at the Bupyeong arsenal and hung today in the bell pavilion is a Song-dynasty bell.
