The Ministry of Culture, Sports, and Tourism has issued Decision No. 1266/QĐ-BVHTTDL allowing Hue Monuments Conservation Center to collaborate with the National Museum of History to conduct archaeological excavations at the Dai Cung Mon Gate site in Hue Imperial City.

After two archaeological excavations of the National Relic of Mount Ban (An Tay Ward, Hue City), experts have discovered a number of vestiges and relics that contribute to confirming that this place is where Nguyen Hue set up Nam Giao Esplanade to sacrifice to “heaven and earth” before ascending the throne. Also, according to the latest archaeological information, experts recommend turning this relic into a special national relic.
