The chief purpose of application of information technologies in representation of archaeological parks is a well-studied subject and the corresponding conclusions are clearly formulated. It is however much less done in their concrete applications. In this paper, we propose a possible scenario for application of information technologies in representation of archaeological parks. This scenario is primarily based on a purposely designed electronic guide and specific projection systems realized by the ARhiMedia group of the Mathematical Institute in Belgrade that is working at the Faculty of Electronic Engineering in Niš. In the design of such projection systems a special attention has been paid to achieving a reduced production price which makes them affordable by archeological parks in Serbia. In the proposed scenario, the data of interests for a visitor are presented in multimedia form including text, photos, drawings, audio and video records and computer generated 3D objects, which is of a particular interest for reconstruction purposes. A purposely designed electronic guide enables the visitor to be independent on the guided tour and allows him to explore the site individually. In this way, the visitor takes an active role in creating the exhibition contents depending his personal interests, previous knowledge, and available time.
