Graphic reconstructions have always accompanied restoration projects related to the study of lost architectural traces. It is difficult to track their history, since in practice they have been an intrinsic part of the evolution of the activity and science of restoration.
3D modelling, graphic and virtual reconstruction as a means of studying and preservation of cultural heritage are still rarely applied for the needs of archaeology in our country. This is a topic which should be subject to continuous and profound investigation. Scientific studies and preservation of cultural heritage would benefit from the preparation of virtual reconstructions, provided the latter obeys certain principles, which warrant the achievement of the required intellectual and technical strictness.
The paper aims to rationalize the actuality and need of such research activity for the needs of cultural heritage. Illustration of the first attempt to perform digital restoration of the southern fortress wall of the Discoduraterae emporium (village of Gostilitsa, municipality of Dryanovo) and the results from it is provided.
