It was originally built in 889AD by Master Doseon. It was moved by Monk Chanjeub and Zen Master Jeungam in 1748 to where it now sits on Ansan Mountain.
The complex holds about thirteen buildings. The first building on the left after entering is The 3000 Buddhas Hall and is by far the most impressive in size. It stands about three stories high and it is interesting to note that no nails were used on the building during the original construction or the restoration in 1991. It is the largest wooden building in Korea.
