A bulgam is the room or the house to enshrine the Buddhist image and smaller than other general buildings.
The Stone Buddhist Niche in Unjusa Temple is the distinctive example which was built outdoors.
This is located at the valley named Datapbong Peak, which means the highest among the peaks.
As the name tells, one can see a lot of Buddha images and pagodas on the way to the peak.Two walls at the north and the south of the niche, in the shape of rectangular, are stuffed with longish stone slab while the air can go through those in the east and the west direction.
On the top of the walls, leveled-out stones are layered as if they form hip-and-gable roof in the wooden construction.
Two Buddha images are put within the niche and with an extraordinary position of sitting back to back.
The decoration method applied to the Buddhist images is not so refined but reflects the local traits that were developed during Goryeo Dynasty.
It is very rare to find such a huge stone Buddhist niche in Korea and the position of the Buddhist images within the shrine.
Such distinctiveness of this niche attaches a great value to itself.
