Established in the 8th century on the slopes of Mount Toham, the Seokguram Grotto contains a monumental statue of the Buddha looking at the sea in the bhumisparsha mudra position. With the surrounding portrayals of gods, Bodhisattvas and disciples, all realistically and delicately sculpted in high and low relief, it is considered a masterpiece of Buddhist art in the Far East. The Temple of Bulguksa (built in 774) and the Seokguram Grotto form a religious architectural complex of exceptional significance.
