Two granite rocks in the shape of triangle stand face to face on both sides of the lane from Naegang-ri of Kumgang County to Phyohun Temple, and the right one is Sambul Rock.
On the rock are carved the image of Sakyamuni in the centre, the image of Miruk on the right, and the image of Amita on the left. The images are 3.7 metres high each.
