Seosan

Seosan is a city in South Chungcheong Province, South Korea, on the Taean peninsula facing the Yellow Sea. Near it is the Rock-carved Buddha Triad of Seosan, carved into a cliff in the late Baekje period, around the early seventh century, and known for the warm smiles of its figures. The triad is a National Treasure of South Korea and lay on an old route between Baekje and China.
