The project "Preservation, renovation, restoration of Tu Duc Mausoleum", including Dien Hoa Khiem (Royal palace for worship and ceremonies), Minh Khiem Duong (Ceremonial pavilion), On Khiem Duong (Pavilion for royal functions), rampart, gate, and screen wall is being implemented by the Hue Monuments Conservation Center (HMCC).

After having gone through 13 king reigns, the Nguyen Dynasty left to Hue heritage a huge volume of mausoleums and royal tombs, many of which bring unique historical, architectural, and cultural values such as Gia Long, Minh Mang, Tu Duc, and Khai Dinh royal tombs, etc. This is one of the factors helping Hue to be always attractive to tourists.
