Experts from the Institute of Archaeology have asserted that archaeological monitoring is indispensable during the construction of the O Cho Dua intersection in Hanoi.

At an October 22 conference, Dr. Bui Van Liem proposed that the management board of the Cho Dua-Hoang Cau section of ring road 1 project promptly informs relevant agencies and experts of any changes that may affect the archaeological site, as prior research was conducted in just a small section of the site.

Since August this year, the institute has conducted studies in an area of 80 cubic metres in the project site, which covers the La Thanh Thang Long relic.

Based on ancient Thang Long-Hanoi documents, many researchers believe that the La Thanh Thang Long relic was among the gates to Hanoi’s ancient citadel, which was called Truong Quang.

To date, ancient traces of have been found in three out of the four construction pits.

Further research is being conducted to help experts give their final conclusion.-VNA
