Some research findings of relic site of Thăng Long Royal Palace in 18 Hoàng Diệu street (Hanoi)

Abstract

The Thăng Long Royal Palace relic site in 18 Hoàng Diệu street is located within a vast area, of which the area being excavated spans over 19,000 square meters. Exposes of the relic were discovered at four sites, namely A, B, C, D (in accordance with archeological signs). In order to carry on research and assess in a systematic manner all relics unearthed at these sites, the first crucial task is to determine the standard space and location of such architectural sites. To that end, it is necessary to establish a benchmark and to create a standard national climax and altitude net, which is equivalent to the international standard, at the relic site. Researchers referred it as the altitude net of Thăng Long Royal Palace. Though it is a new task in Vietnam pertaining to the creation of a national climax and altitude net at archeological sites, it has been rather popularly used in many countries, particularly in Japan and the Republic of Korea.This article briefly presents the significance of a standard altitude net for the research, evaluation and creation of a scientific map of architectural relics of the Thăng Long Royal Palace site in consistence with international urban archeological standards; at the same time, it introduces some initial research findings related to relics of Lý-Trần dynasties after two years of joint work between Vietnamese and international archeologists. Special attention in this paper is drawn to royal halls and buildings of the ancient Thăng Long Royal Palace.
