Dong Khanh was the ninth king of the Nguyen Dynasty. Hue Relics Preservation Centre, the project constructor, said it would take four years and VND76.3 billion (US$4.2 million) to upgrade the surroundings and put systems in place to ensure upkeep of the tomb and other works like the Cung Mon (main gate).

The funds will be drawn from the provincial budget and will be used to purchase new firefighting and prevention equipment as well as other safety measures against thunderstorms.

The tomb has been closed to the public for several years pending restoration work because of its rundown condition.
