The paper deals with the results of a research project, LandLab Project, finalized at the reconstruction of ancient landscapes. The use of Internet for presenting the results of the scientific research is discussed through the presentation of two web applications, which have been implemented by the Laboratory of Archaeological Computing of the Dept. of Cultural Heritage - University of Lecce, Italy: the WebGIS of the pre-Roman settlements of the Salento region and WODOS, the on-line version of the ODOS excavation data management system. The web-based applications are aimed at developing new approaches to the problem of data preservation and data dissemination. They use the methods and technologies available in the field of Information and Communication Technology for the transfer of data, information management systems and multimedia communication in the reconstruction of ancient landscapes and cultural systems. The project is unique in the geographical context in question here, in that it represents the first thematic laboratory for research into the ancient landscape completely based on Web Programming and Internet Technology
