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).

Subsequent to more than 2 months of exploration and archaeological excavation of the Lieu Coc Twin Towers monument, the experts judged that there are 2 main tower temples in the monument, with no sign of a third tower temple. If so, then the Lieu Coc Twin Towers monument is a special and sole monument in the system of Champa Tower temple monuments with 2 main worship towers.

Few people know that within the premises of the Phuong Duc Primary School at 245 Bui Thi Xuan, Hue City, there exists the only remaining mountain and river deity worship place in the country today - the Son Xuyen Esplanade.
