The tomb was accidentally discovered in August 1955, when the Hong Kong Government was levelling a hill slope for the construction of resettlement buildings at Lei Cheng Uk Village (present-day Lei Cheng Uk Estate).
The tomb was then excavated by members of Hong Kong University and workers of the Public Works Department, Hong Kong under the supervision of Professor F.S. Drake, former head of the Chinese Department at the University of Hong Kong.
After excavation, the tomb and an exhibition hall were formally opened to the public in 1957.
In November 1988, the Han Tomb was declared as a gazetted monument by the Hong Kong Government, and it is now protected and preserved permanently under the Antiquities and Monuments Ordinance.

Due to conservation reasons, visitors have not been able to enter the tomb itself since the mid-1980s.
They now have to view it through a glass panel at the entrance passage, and the tomb is sealed in a temperature and humidity controlled environment.

The tomb, which had been protected by concrete, waterproofing layers, topsoil and turf, suffered from rainwater leakage problems and its protection underwent a renovation project completed in 2005.
The renovation works included the building of a canopy to cover the tomb.

3D Laser Scanning Technology in digital recording of structures was applied to capture 3D images of the structure.
