Stone
The Buddhas are carved in relief on a cone-shaped rock. Two are missing on the west side, inferring there were originally nine. The sculpture is believed to date from the early Goryeo dynasty (918–1392) and was listed as Treasure No. 461 in 1968.
The figures are too worn to decipher details, but it is observable that the Buddhas on the north and east sides sit in full lotus positions. The four southward facing Buddhas in the photo stand wearing monastic robes of different styles, judging by the incised lines depicting them. Their hands alternate between having both hang by their sides or raised right hands.
