HA NOI (VNS)— "The four-year UNESCO/Japanese Funds-in-Trust project has created a solid foundation for future co-operation in heritage conservation and management," noted Katherine Muller Marin, head of the UNESCO office in Ha Noi, at a meeting to review the project held in the capital yesterday.

Since 2010, the Thang Long- Ha Noi Heritage Conservation Centre in conjunction with the Tokyo-based National Research Institute for Cultural Properties and the UNESCO office in Ha Noi have conducted research into preserving relics. The team has also set up a plan and applied an experimental GIS information system at the Thang Long Citadel.

Historical and archaeological research has helped clarify some of the history of the establishment and development of the Thang Long Royal Citadel in the 9th century.

Archaeological evidence found by scientists proves that the old architecture at the royal citadel was not only influenced by ancient Chinese citadels, but also possessed special traditional cultural features.

Scientists have figured out the best way to preserve objects at the site is to use soil. They have succeed in an experimental preservation method of using sand to cover archaeological objects buried deep under the earth. They have also figured out the physical and chemical features of many pieces of wood found at the site.

Experts in Japan and Viet Nam have carried out a series of training courses and information exchanges during the period.

"...today's challenges are too complex for any organisation or individual to respond to on their own terms," Marin stressed on the joint project.

"Let us hope that the ties we have already established remain strong and continue to grow as we advance towards the ultimate goal of sustainable development."

Nguyen Thi Bich Ngoc, vice chairperson of Ha Noi People's Committee, shared her opinion on the need for co-operation among experienced experts.

"We profoundly understand that preserving a world heritage site inside a developing city is a proud and challenging task," she said. — VNS
