Seosan Maaesamjonbulsang

(Three Buddha images on a rock cliff)

 Seosan Maaesamjonbul is a relief carved on a big rock which stands to the left of Powonsa Temple in Yonghyon-ri, Unsan-myon at the foot of Mt. Kayasan.
Discovered in 1958, this is considered to be the most outstanding depiction of Buddhas in Korea. In the middle is the Sakyamuni Buddha flanked by thinking Bodhisattvas sitting cross- legged.  
The main Buddha is 2.8 meters tall and the relief is believed to be the work of a mid-sixth century Baekje artist.
The facial expressions of the Triad appear differently with changes in the direction of light.
