The Inner Citadel and Nam Giao Altar were designated in 1962 as national heritage by Decision of the Ministry of Culture of the Democratic Republic of Vietnam and are protected under the Law on Cultural Heritage of 29/06/2001. The nominated section of La Thanh Outer Wall is in the process of being similarly protected. The buffer zone is protected by the Law on Environmental Protection of the Socialist Republic of Vietnam, number 52/2005/QH11, Chapter 4, Article 31 of 2005. The property is directly managed by the People’s Committees of the relevant communes for the particular component sites, under the Management Board of the Citadel of the Ho Dynasty established by Decision 2264/QD-UBND (30 July 2007).
A comprehensive five–year Management Plan for the property was submitted in November 2010. The control of urban development near the Inner Citadel, in Vinh Loc town particularly along the axis between the Inner Citadel and Mount Don Son, and in the buffer zone generally should receive specific attention so as to protect all view lines along the axes between topographical features, and views within the area enclosed by the line of the outer wall and the Ma and Buoi rivers. Special attention is needed for the development of a risk-preparedness and management strategy and a strategy for involving local people in the protection and management of the property. The local authority and people are working closely for the preservation and protection of the property through a training and public-awareness raising programme.
