The recognition was approved under a decision signed by Deputy Prime Minister Mai Van Chinh as part of the 14th round of national treasure designations in 2025.
The five artefacts include a 12th-century stone stele, a 14th-century stone Buddhist altar, Tran-era cliff carvings of 18 Arhats, a 1472 bronze book from the reign of King Le Thanh Tong, and three Later Le stone steles.
Authorities said the additions underscore Ninh Binh’s deep historical and cultural heritage while placing greater responsibility on conservation and heritage promotion in tandem with local socio-economic development.
Following the merger of Ninh Binh, Ha Nam and Nam Dinh provinces, the expanded Ninh Binh now hosts thousands of historical and cultural sites, including the Trang An Scenic Landscape Complex, which was recognised by UNESCO as a World Cultural and Natural Heritage site in 2014.
