When it was first built by State Preceptor Myeongbon in the sixth year of the reign of King Wonjong (1265) of Goryeo, Cheongnyongsa Temple was only a small hermitage named Daejangam. The hermitage was expanded and renamed Cheongnyongsa by Buddhist Monk Naong in the 13th year of the reign of King Gongmin (1364) of Goryeo. Legend has it that Naong renovated the temple after he saw a blue dragon, shrouded in clouds, descending from heaven. Daeungjeon Hall is presumed to have been reconstructed during the late Joseon Dynasty. The hall comprises 3-kan (a unit of measurement referring to the distance between two columns) front space and 4-kan side space, and it has a hip and gable roof called paljakjibung. Multi-cluster brackets are placed not only on the column tops but also on the outer tie beams between the columns. This building style is known as dapo style. Brackets are elaborately engraved with lotus flower and bud designs, representing a typical feature of late Joseon architecture. Interestingly, however, columns are not adorned at all. Inside the hall a Buddhist temple bell, cast in the 15th year of the reign of King Heonjong (1674), is preserved. The inner ceiling is latticed.
