Tongdosa
Tongdosa (Hangul: 통도사; lit. Salvation of the World through Mastery of Truth) is a head temple of the Jogye Order of Korean Buddhism and in the southern part of Mt. Chiseosan near Yangsan, South Korea.
Tongdosa was established by the monk Jajang-yulsa after returning from Tang China in 646 AD, during the reign of Queen Seondeok of Silla. It thrived throughout the Later Silla and Goryeo periods (918-1392), when Buddhism was the state religion, and remained strong even during Joseon.
Tongdosa is reputed to house several relics of the Buddha himself, including a robe, a begging bowl, and a bone from his skull, all relics that Jajang-yulsa brought back from the travels to Tang China he undertook in 636 to study with ten other monks.
Tongdosa is one of the Three Jewels Temples and represents Gautama Buddha. (Haeinsa, also in South Gyeongsang Province, represents the dharma or Buddhist teachings; and Songgwangsa in South Jeolla Province represents the sangha or Buddhist community.)
