It is the origin of Sagulsan division among 5 lessons 9 mountains of Silla Seonjong.
Gulsansa Temple was built by Gulsa master Beomil in the 13th year of King Munseong of Silla (851). According to Jodangjib, Beomil's grandfather was Myeongju governor Kim Sul Won, and mother's maiden name was Moon, and he was born after 13 months. He became Buddhist monk in 15, and received upasampada when he was 20 years old, followed prince Kim Ui Jong to study in Tang, came back to Silla in the 9th year of King Munseong(847). While he was cultivating his spirituality in Baekdalsan Mountain, Myeongju governor Mr.Kim asked him to spread Buddhism. Then he built Gulsansa Temple, and became the progenitor of Gulsanmoon.
Gulsansa Temple prospered with the support of Goryeo local family, and closed after early Joseon, but there is no accurate record of the history.
The site of Gulsansan Temple was turned into farmland, therefore an accurate scale or building arrangements are unrecognizable, but when the urgent excavation was conducted for flood damage from typhoon "Rusa" in 2002, the temple site was 140 from east to west and 250m from north to south. Also, there are 3 cultural layers, the first and second layer are lost, but third layer is still remaining. The sites of sanctuary, the monk's dormitory, the corridor and the pagoda were verified.
Currently, treasure no.85 Gulsansajibudo, treasure no. 86 Flagpole Supports of Gulsansa Temple site(largest in Korea), cultural material no.38 Seated Stone Buddha of Gulsansa Temple site are remaining at the site, along with Seokcheon (well) and Hakbawi which tells the story of Beomil's birth.
