The former imperial city Hue is going to install an audio guide system in five languages to serve visitors at its attractions.
Phan Thanh Hai, director of the Center for Preservation of Hue Former Citadel Relics, said audio guides are being planned for major tomb sites and the royal citadel.
Hue was the seat of the Nguyen Dynasty from 1802 until the end of feudal Vietnam in 1945.
Hai said the system will be developed with private investment and tourists will have to pay to access the guides, apart from entrance tickets.
It is unclear when the new service will be launched and which other languages, besides English, will be chosen.
The center is also going to introduce e-tickets and free Wi-Fi at the sites soon.
Thua Thien-Hue Province, which is known for the imperial city, pagodas and other natural attractions, received around 58,000 tourists during the National Day weekend between September 2 and 4.
Foreign visitors during the first eight months increased 36.5 percent from a year ago and accounted for more than half of nearly 1.8 million tourists coming to the province.
