The US$1.1 million project aims to build a suitable management system for the benefit of long-term citadel preservation and sustainable development in the locality, said Nguyen Van Son, Director of the Thang Long-Hanoi Heritage Conservation Centre, at a seminar in Hanoi on December 18 to review the four-year project.

In 2010, with the support of Japanese partners, the Vietnam Institute of Vietnamese Studies and Development Sciences discovered new facts about the citadel.

Based on its name and architecture, scientists have proven the similarity in planning shared by the Thang Long Citadel and other citadels in Southeastern and Northeastern Asian countries.

The project has also helped young Vietnamese archaeologists access advanced methods while promoting the development of Vietnam’s urban archaeology.

Thanks to Japan’s machinery and equipment assistance and consultations, a geographic information system has been established to support the management of the heritage site.

Various books on the special values of the citadel have been issued.

The Thang Long Citadel was recognised by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) as part of the world cultural heritage in 2010.

The site was credited with its three special characteristics: the length of cultural history, the continuity of the citadel as a power centre and a variety of relics remaining intact.

Also on December 18, the Hanoi City People’s Committee presented certificates of merit to the UNESCO Office in Vietnam and the Tokyo Research Institute of Cultural Properties for their contributions to protecting the heritage site.
