Archaeologists have found traces of ancient Vietnamese civilisation from 3,500 to 4,000 years ago at the Co Loa citadel in the Hanoi suburbs.
     One of the archaeological sites covers 132 sq.m in Lo Khe village, Dong Anh district, where archaeologists unearthed objects believed to belong to the Bronze Age. They included 372 pieces of earthenware and a number of pieces of stone jewellery and tools. A basalt axe, a knife-grinding stone, and pieces of nephrite bracelets, typical of the Phung Nguyen culture existing between the 15th and the 20th centuries BCE were discovered.
     Archaeologists also discovered several pits of different sizes, which contained pieces of earthenware. Archaeologists plan to expand the site to 3,000 sq.m in the near future as part of an archaeological research programme in Hanoi through 2010.
