A ceremony to announce the recognition was held in Nam Nhun district of the province on March 5.
King Le Thai To, real name Le Loi, was founder of the Later Le dynasty (1428-1788). In 1431, the king ordered the creation of the stele on a cliff at the Da River’s north side at the foot of Pu Huoi Cho mountain. It served as a warning to rebels in the country.
The stele was named a national historical site in 1981. It was moved to a temple dedicated to King Le Loi, 500 metres from the previous place, for preservation in 2012 and officially listed as a national treasure in late 2016.
The Le Loi King memorial site was recognised as national historical site in early 2017.
