Abstract

During urban formation from 1802 to 1945, themountain systems and natural waters were closely utilised inurban design of Hue City which was a relevant example ofurban planning for sustainable development. Hue Citadel wasbuilt as an unusual combination of human and nature, theprinciples of Western military architecture meeting the ideologyof Eastern philosophy and traditional architecture of Vietnam.The fortification model of Sébastien Le Prestre de Vaubanharmoniously united with local natural elements to create theidentity of the ecological system which was considered as anappropriate local technology for environmental self-regulating.<br>In the last decades, Hue City has been experiencing mainchanges by the impacts of urbanization such as the increase inpopulation, changing lifestyle, environmental pollution, flood,causing heavy variation of the characters of the traditionallandscapes, and harming of the heritage. Most of the precedentdesigns and ideas tend to be ignored and broken down.Understanding and identification of characters of historicalfabric, landscape value, and urban structure are very importantto the preservation of a sustainable model which orients towardsthe Feng Shui methodology. Since 1993, the complex of HueMonuments was inscribed on the List of World Heritage byUNESCO.
