Chilsadang is a place of prayer and worship. It is an ancestral shrine and location of spirit tablets for the seven gods of heaven at Jongmyo Shrine. The gods enshrined here include the gods of gates including entrances and exits, halls, kitchens, and other rooms, roads, and those who have died of diseases.
People came here to pray to the gods hoping that royal and state affairs would occur without difficulties or problems.
These rituals to the seven gods of heaven involved both traditional religion practices and Confucian philosophy.
