The historic site, situated at 18 Hoang Dieu, Ba Dinh district, Hanoi, was the centre of the Thang Long Royal Citadel during the Ly, Tran and Le dynasties.
Following the results of research carried out during period 2004-2008, the unique historical value of the Thang Long Royal Citadel was confirmed by the discovery of various connected archeological layers, reflecting the continual succession of dynasties involved in the construction of the citadel.
The archeologists and historians working at the site have recently discovered structural modifications dating back 1,300 years, with the activity of each ruling dynasty reflected in an array of archeological designs.
They also unearthed millions of ancient artifacts, including porcelain items originating from China, Japan and West Asia, reflecting cultural and economic exchange between Thang Long citadel and other countries across thousands of years of history.
Documents arguing the royal citadel’s case for recognition as a world cultural heritage site have arrived in Paris for consideration by the United Nations Educational, Scientific and Cultural Organization (UNESCO).
