This paper is a review of the modelling of two edifices located in a city which developed on the vestiges of a Roman city during antiquity endowed in the 4th century with a military camp. The term <i>castellum</i> is used for the first structure. A second structure concerns the remains of a castle dismantled at the end of the 17th century, which was generally known only by an engraving in perspective made shortly before its demolition, and the cadastral matrix that had preserved the traces of its right-of-way. It is a Renaissance castle built in the 16th century by the Württemberg family in the northeast corner of the ruins of the <i>castellum</i>. The projects contain a first part of data analysis and interpretation based on available documents. Similar sites close in terms of architecture, geographical location and construction period were also visited to get inspiration from them and to be able to make proposals for restitution. Despite the lack of data available, the multidisciplinary aspect of these projects is very important. In fact, the experience of archaeologists and the monitoring of modelling throughout its progress is essential to work out models that are both justifiable, at the level of the proposals made and sufficiently complete to be able to be highlighted. Once the models validated, they are integrated in a virtual way into the contemporary urban environment, through an interactive virtual tour. This paper reviews the principles implemented during the modelling, the rendering and the valorisation of the models thru virtual tours and AR/VR implementation.
