Yaksajeon Hall, which enshrines Bhaisajyaguru Buddha (the Buddha of healing and medicine), is situated to the west of Daeungjeon Hall, Jeondeungsa Temple. The temple is presumed to have been built by the Buddhist monk Ado in 381 (the 11th year of the reign of King Sosurim of the Goguryeo Dynasty), though very little is known about its history prior to the mid-Goryeo Dynasty. It is said that the temple was burnt to the ground by two large fires in 1605 (the 38th year of the reign of King Seonjo of the Joseon Dynasty) and in 1614 (the 6th year of the reign of King Gwanghaegun), and that it was fully restored to its original appearance between 1615 and 1621 (the 13th year of the reign of King Gwanghaegun). Although the exact year of the hall’s construction is not clear, according to the Records on the Renovation of Daeungjeon Hall and Yaksajeon Hall, the roof tiles for both Daeungjeon and Yaksajeon Halls were replaced in 1876 (the 13th year of the reign of King Gojong of the Joseon Dynasty. Judging from the construction style of Yaksajeon Hall, which is similar to that of Daeungjeon Hall, it is assumed that former was built during the mid-Joseon Dynasty. The hall measures 3 kan (a unit of measurement referring to the distance between two columns) at the front and 2 kan on the sides, and has a hip-and-gable roof resembling the character 八 when viewed from the side. The building’s ceiling has the form of a sharp (#), and features magnificent painted designs of lotus flowers and vines in its background. As Yaksajeon Hall was built with an unusual type of bracket system to support the eaves, it is regarded as an important cultural asset for research on the construction style of the time.
