This is the royal tomb of Queen Jeongseong (貞聖王后, 1692-1757), from the Seo family. She was the lawful wife of the 21st King Yeongjo of the Joseon Dynasty. Queen Jeongseong got married to Prince Yeoning, the second son of King Sukjong, in 1704. She was installed as Queen when Prince Yeoning ascended the throne to be King Yeongjo following the weak and heirless King Gyeongjong. In the records of the Queen’s life, King Yeongjo expressed his gratitude to Queen Jeongseong, saying that she always welcomed him with a smiling face during her entire 43 years of royal residency, and was fully devoted to her superiors. He added that she was not indolent at all and did her utmost to enshrine the ancestral tablet of his birth mother, Sukbin, from the Choi family.
