Jeondeungsa is a Buddhist temple on Ganghwado in Incheon, next to Jeongjoksanseong Fortress. The grounds hold Daeungbojeon Hall, Yaksajeon Hall, a bell from Song China, and an old ginkgo tree. Entry is free, and in autumn the large ginkgo tree stands out. Within the grounds, Jeongjoksan Sago, which stored the Annals of the Joseon Dynasty, connects to Jeongjoksanseong Fortress, where French forces were repelled during the 1866 Byeonginyangyo campaign.
