THANH HOA — Archaeologists have just asked local authorities of central Thanh Hoa Province to step up their efforts to prevent land erosion at Nam Giao worship platform in the complex of the Ho Citadel.

The relic is located in the middle of Don Son Mountain and is thus vulnerable to landslides during rainy season.

Professor Tong Trung Tin, director of the Viet Nam Archaeology Institute, said that the scientists had excavated over 50 per cent of the area north of the platform and helped unveil five storeys of the platform.

Vuong Van Viet, deputy chairman of the provincial People's Committee, promised that the authorities would apply protection solutions soon.

The platform was built in 1402 during the Ho Dynasty.-VNS
