Washington, Oct 5 : Excavations at two regions in Vietnam have revealed findings from the Stone Age and Bronze age, which includes tombs and artifacts.
Following excavation work at the Dong Trong I and II grottoes in the northern province of Quang Ninh, archaeologists affirmed that this was the tomb of Stone Age humans belonging to the Ha Long culture, dating back to 3,000 - 4,000 years ago.
Meanwhile, bronze work excavated at Go Bong in the midland province of Phu Tho has shed light on the Phung Nguyen culture (about 3,500-4,000 years ago).
Last year, a major dig at the Co Loa's Thuong Temple on the outskirts of Ha Noi revealed that it was a major centre of activity during the An Duong Vuong and Ngo Quyen dynasties. Much of the metalwork for Co Loa Citadel (built in the year 257 BC) was also made there.
Together with the Illinois University in the US, excavation work at Luy Hao-Thanh Trung revealed that the Co Loa Citadel was the site of an earlier structure, and that it had subsequently been enlarged four times.
Meanwhile, after the fifth excavation of the Ho Citadel in the central province of Phu Yen during the 5th-7th century, archaeologists from the institute and the Phu Yen Museum discovered that the Cham culture had reached a high degree of sophistication.
