There are two different theories concerning the exact date of the construction of Bulgapsa Temple. One is that the temple was built by Monk Marananta from India in the first year of the reign of King Chimnyu of Baekje (384). The other is that it was built by Monk Haengeun during the reign of King Mu of Baekje. Daeungjeon (the main Buddha hall) is a place where an image of Sakyamuni Buddha is enshrined. This temple's Daeungjeon is believed to have been built prior to the 18th century, and to have been repaired during the reign of King Yeongjo of Joseon, in the light of a recovered roof tile bearing the Chinese characters signifying the 29th year of Geonnyung, which was the same as the 40th year of King Yeongjo (1764). The hall was repaired again in the third year of King Seonjo’s reign (1909). It comprises 3-kan (a unit of measurement referring to the distance between two columns) front space and 3-kan side space, with multi-cluster brackets and a hip and gable roof called paljakjibung, on the top of which are small images in the shape of a stone pagoda and a linden. Dragon heads are carved on the upper part of the two columns in the center section. The door in the center is decorated with elaborately carved chrysanthemum and lotus flower designs. Inside the hall corner brackets are sculpted with dragon heads and the ceiling is latticed. This Buddha hall, decorated with beautiful patterns and sculptures, well retains the method and style of late Joseon wooden structures.
