Ho Dynasty Citadel
The Citadel of Ho Dynasty built in 1397, composed of the Inner Citadel, La thanh Outer Wall and the Nam Giao Altar covers 155.5 ha, surrounded by a buffer zone of 5078.5 ha. It is located in accordance with geomantic principles in a landscape of great scenic beauty between the Ma and Buoi rivers in Vinh Loc district, Thanh Hoa province of Viet Nam.
The Inner Citadel constructed of large limestone blocks represents a new development of architectural technology and urban planning in an East Asian and South-East Asian context. It demonstrates the use of architectural elements in terms of space management and decoration designed for a centralized imperial city in order to show a concept of royal power, based on the adoption of the Confucian philosophy within a predominantly Buddhist culture.
Being the capital of Viet Nam from 1398 to 1407 and also the political, economic and culture center of the North Central Vietnam from the 16th to the 18th century, it bears an exceptional testimony to a critical period in Vietnamese and South-East Asian history when traditional kingship and Buddhist values were giving way to new trends in technology, commerce and centralized administration.
