The Seonjeongneung is the burial grounds of two Joseon Dynasty kings and one Joseon queen. The westernmost tomb belongs to King Seongjong (r. 1469–1494), the ninth king of the Joseon dynasty. His first wife, Queen Han, died at age 18 and is buried near Munsan, north of Seoul. His second wife, Queen Jeonghyeon (貞顯王后, 1462–1530), from the Yun family, is buried here because she gave birth to the king's second son (the future King Jungjong) in 1506.
