Bricks, tiles, decorative items and royal house-wares were also discovered at the 50 sq. m excavation site, said Pham Nhu Ho, Head of the Archaeology Institute’s Historical Archaeology Section.

He added that these artifacts, which are still intact, have similarities to those unearthed in Hanoi’s Thang Long citadel, which housed relics of the Tran Dynasty.

The findings expose important depth for archaeologists to dig further down to search for more artifacts at the area, Ho said.
