Constructed by a Buddhist monk known as Wonhyo in 673 (the 13th year of the reign of King Munmu of the Unified Silla Period), Jangansa Temple consists of a main hall, Daeungjeon, and other buildings including Myeongbujeon Hall, Eungjinjeon Hall and Sansingak Shrine. Notably, Daeungjeon Hall of Jangansa Temple is known to be the oldest building with multi-bracket sets in Busan, its construction and restoration dates having been precisely recorded in diverse ancient documents including Jangansa Daeungjeon gi (Records on Daeungjeon Hall of Jangansa Temple) written by Kim Bang-han. According to these records, Daeungjeon Hall was originally built in 1654 (the 5th year of the reign of King Hyojong of the Joseon Dynasty), and was repaired in 1948. The colorful decoration on the eaves was repaired in 1975. The building is relatively taller and more imposing than other buildings in the temple’s precincts, displaying impressive appearance as the central building of the temple. The building is regarded as highly valuable as it exhibits a number of interesting architectural features such as the sharp curves on the roof, the structure of the bracket system, the composition of the doors and windows, and the tall canopy ceiling. Furthermore, its overall structure and the multi-color paintings on the building are preserved in very good condition.
