Janggyeongsa Temple is located in Namhansanseong Fortress. Namhansanseong Fortress, which protected Seoul along with Bukhansanseong Fortress, was built at the same time as Janggyeongsa Temple in 1638, during the 16th year of King Injo. Warrior monks from all eight provinces throughout the country helped with the construction. Janggyeongsa Temple is the only remaining temple among nine such temples where military groups made up of monks stayed for trainings.
