The Seokguram Grotto is a hermitage and part of the Bulguksa temple complex. It lies four kilometers east of the temple on Mt. Tohamsan, in Gyeongju, South Korea. It is classified as National Treasure No. 24 by the South Korean government and is located at 994, Jinhyeon-dong, Gyeongju-si, Gyeongsanbuk-do. The grotto overlooks the Sea of Japan and rests 750 meters above sea level. In 1962, it was designated the 24th national treasure of Korea. In 1995, Seokguram was added to the UNESCO World Heritage List together with the Bulguksa Temple. It exemplifies some of the best Buddhist sculptures in the world.
The Seokguram grotto is said to have been built by Kim Daeseong and originally called Seokbulsa. Construction began in 742 when Kim Daeseong resigned his position in the king's court or in 751, the 10th year of the reign of King Gyeongdeok of Silla. This time period was the cultural peak of Unified Silla. The grotto was completed by the Silla court in 774, shortly after Kim's death. An old legend stated that Kim was reincarnated for his filial acts in his previous life.
