Jongmyo, in Seoul, is a royal shrine where the mortuary tablets of deceased royal couples are kept, and is an important site symbolizing the fundamentals of the existence of a state along with Sajikdan Altar, which is the altar for the national soil and grain ceremonies.
The regular ancestral rituals were held at Jongmyo in the first month of each season, i.e. January, April, July, and October, while extraordinary rituals were held on special occasions. Since 1945, the ritual has been held only once a year, on the first Sunday of May. The ritual is held in a solemn atmosphere.
The ritual is carried out in a way so as to entertain the spirits of the dead royal ancestors. The procedure for the ritual is as follows: Chwiwi (placing of ancestral tablets), Yeongsin (greeting the spirits), Haengsinnarye (King's obeisance to ancestral tablets), Jinchan (presenting the spirits with food), Choheollye (first obeisance), Aheollye (second obeisance), Jongheollye (last obeisance), Eumbongnye (partaking of sacrificial food), Cheolbyeondu (overturing of ritual dishes), Mangnyo (incineration of prayers). The King had to behave discreetly for four days and keep his body clean for three days before the ritual.
Jongmyo Jerye featured grandeur and solemnity as a ritual that set an example for the people of a Confucian society that attached particular importance to etiquette.
The ritual, along with the music associated with it (Important Intangible Cultural Heritage No.1), was registered with UNESCO in the Representative List of the Intangible Cultural Heritages of Humanity in May 2001.
