Summary In this article, the evaluation of deterioration stage of five archaeological waterlogged woods excavated at Hoa Lu ancient relic site, Ninh Binh in 2021. The results of wood species identification and assessement of the current detertioration status showed the diversity of wood species and the degree of damage. The classification results showed that there are 04 species: Chac Khe (Dysoxylum sp.), Cong (Calophyllum sp.), Truong (Pometia sp.) and Tau (Vatica tonkinensis A. Chev.). The destruction assessment results showed that 5 wood samples were divided into 3 groups of deterioration. The Chac khe was under heavily damaged while the Cong was moderately deteriorated. The Truong and Tau were only slightly decomposed. The research results provided the basis for future establishing a long-term conservation treatment process for each type and derterioration degree of historical woods.
