The Da Nang administration Thursday submitted an application asking the government to recognize as "National Treasure" three Champa kingdom relics in the central coastal city.
Tra Kieu and My Son E1 are sandstone monuments built between the 7th and 8th centuries while the bronze statue of Buddhist goddess Tara dates back to the 9th century, according to the application submitted to the Ministry of Culture, Sports and Tourism.
All three relics are original and have no copies as of present, the application said.
My Son E1 is the only undamaged Champa monument left in Vietnam and can provide important insights into the culture, religion and architectural characteristics of the Cham civilization.
The monument is also the only one of its kind that contains descriptions of people, nature, and daily activities of the ancient Cham people.
It is also considered by experts a typical example of the first established style of Cham sculpture, news website Dan Tri said in a report Thursday.
Tra Kieu monument, meanwhile, points to the existence of a Champa town and religious places more than 1,000 years ago in what is now Tra Kieu village in Da Nang.
Archeologists say the bronze statue of Tara statue is typical for Buddhist statues found in the biggest Cham pagoda, the Dan Tri report said.
So far, experts have not been able to figure out how the statue was made, it added.
All three relics are being exhibited at the Cham Sculpture Museum in Da Nang.
Champa was an Indianized kingdom that controlled Vietnam's current southern and central regions from the 7th century to 1832.
