She is believed to have been a 16-year-old princess when she arrived in the Gaya Dynasty (42-532) by boat, she married King Suro, and bore nine princes. Two of them followed the queen's family name by the order of King Suro, becoming a forefather of Heo family. Her tomb has a 5m-high earthen mound. The thin stone fence is protecting the tomb, with a long stone in the front erected as an embankment. In the middle is the monument, inscribed with two-line words to describe who was buried. As affiliation buildings, Sungboje, a building used to prepare memorial services, Oesammun, and Hongsalmun are located on the grounds. According to the record, the preservation area was enlarged in 1446, the 28th year of the reign of The Great King Sejong and the tomb was robbed during the during the 1592 Japanese Aggression. It was repaired in 1641, the 19th year of the reign of King Injo (1623-49) of the Joseon Dynasty (1392-1910). The installation is rather simple for a royal tomb. Considering the fact that it was built during the same period with the tomb of King Suro, the interior structure might have been a stone-lined tomb.
