Before the Roman annexation of Numidia, Thugga had existed for more than six centuries and was, probably, the first capital of the Numidian kingdom. Criterion (ii): The site of Dougga is an outstanding example of the birth, development and history of an indigenous city since the second millennium BC. Whilst retaining its largely Numidian urban fabric, Thugga therefore took on the aspect of a Roman monumental city. A proposal for the boundary of the site of Dougga was submitted to the National Heritage Commission for the creation of the Cultural site of Dougga and its landscape. The PPMV is the management tool that guarantees the preservation of the archaeological site of Dougga and enables the control of all eventual modifications in its immediate environment.
