History of Geumsan Mountain
A great Buddhist priest named Wonhyo Daesa built Bogwangsa Temple in 638 (3rd year under the reign of King Sinmun of Silla Kingdom) and named the mountain Bogwangsan.
Centuries later, Taejo Lee Seong-gye, the first king of Joseon Dynasty, became a king after praying for 100 days in the mountain. He promised to cover the whole mountain with silk if he becomes king. However, he couldn’t find a silk blanket big enough to cover the mountain, so he named the mountain Geumsan (Silk Mountain) instead.
