Mt. Daemosan behind Heonilleung Royal Tomb was originally called Halmisan (meaning grandmother in Korean) because it resembles the shape of an old lady. Daemosan Mountain embraces Heonilleung Royal Tomb, guarding the royal tomb.Heonilleung Royal Tomb houses the mounds for two kings of the Joseon Dynasty (1392-1910): King Taejong (1401-1418) and King Sunjo (1800-1834). Heonilleung Royal Tomb possesses numerous stone statues and vestiges, and is a good place to experience the culture of the Joseon Dynasty. Upon entering the grounds, the striking red gate with the taegeuk (yin-yang) symbol appears to draw the line between this world and the one beyond. Passing the red gate leads to a sacrificial building where ancestral memorial services were performed. Behind the sacrificial building is the royal tomb. On the eaves of the sacrificial building are animal sculptures called japsang, which are believed to exorcise evil spirits. There is a pavilion next to the sacrificial building where the tombstone is situated. The royal tomb is surrounded by statues carved in the shape of animals such as tigers and sheep. There is also a statue of a solemn military officer bearing a sword with his horse behind him. The stone sculptures are guardians of the dead king.
