Princess Ngoc Son, whose real name was Nguyen Phuoc Hy Hy (1886–1905), was the daughter of King Dong Khanh – the 8th emperor of the Nguyen Dynasty (1885–1889). She married Commander Nguyen Huu Tien, son of Grand Secretary of Dong Cac Nguyen Huu Thang, a respected high official in the royal court. However, the princess's life was short, as she passed away at the age of 20 after giving birth to a daughter, leaving deep sorrow for her family and the people of the capital.
In 1921, to commemorate his ill-fated first wife, Royal Consort Nguyen Huu Tien built the Ngoc Son Princess Worship Residence on a plot of land of nearly 2,400 m² in the ancient Gia Hoi area, east of the Hue Citadel. Serving not only as a place of worship for the princess, the residence was also the living space for the royal consort, his second wife – Princess Cong Ton Nu Thi Tran, and their seven children. Experiencing over 90 years of historical changes, the garden house is still preserved almost intact thanks to the dedication of generations of descendants, especially Mrs. Nguyen Thi Suong (granddaughter of the royal consort) and her husband – researcher Phan Thuan An.

Although not directly part of the royal palace system, Ngoc Son Princess Worship Residence is closely linked to the history of the ancient capital. This place not only preserves memories of a talented yet ill-fated princess, but is also considered a rare 'family library' containing thousands of ancient books in multiple languages. Precious artifacts such as Khai Dinh era medals, bone 'xam huong' game sets, custom-ordered Chinese ceramics, intricately carved tea trays... are still present today, creating the unique cultural value and special charm of Ngoc Son Residence.
