The Prime Minister has approved more than US$192 million for the plan, of which US$67 million is used to restore and promote the treasured Tran Dynasty historical complex in Dong Trieu district.
US$86 million will be invested to protect the natural landscape of Yen Tu, while the Bach Dang Victory historical site receives US$39 million to boost its tourism potential.
The investment is sourced from the State budget, local budgets, private funding and tourist fees received by the three sites.
Encompassing more than 11,000ha in An Sinh, Trang An, Thuy An and Binh Khe communes, the Tran dynasty complex is home to tombs of eight kings. As one of the most important memorials in Vietnam, the complex was listed as a national cultural and historical vestige in 1962.
The sacred land of Yen Tu in Quang Yen consists of five sections, including the heritage site, service area, social facilities, management and residential areas. It has become known for its 1,000m Yen Tu mountain and the birthplace of the Truc Lam (Bamboo Forest) Zen sect.
Covering 20,000ha, it attracts many tourists and pilgrims from all over the country.
Last week, the Ministry of Culture, Sports and Tourism proposed to the Prime Minister that the site be submitted to UNESCO for world cultural heritage.
Covering 380ha in Uong Bi City, the former Bach Dang battle site recalls the victory of the Vietnamese people under the Tran dynasty over the third Yuan-Mongol invasion in 1288 along the Bach Dang River.
Both the Yen Tu and Bach Dang sites were recognised as Special National Heritage sites last September.
