This paper presents the results of a research project, which was launched in 1999 by the Institute of Archaeological Sciences of the ELTE. Our main goal was to create a register of Hungarian tell settlements. First we collected all available information on tell settlements from the archaeological literature and various museum archives. Following this preliminary data filtering, fifty of the initial 161 Neolithic sites and 116 of the 224 Bronze Age sites were classified as genuine tells or tell-like settlements. After that we determined the accurate location and co-ordinates of the sites using aerial photography called for the construction of a GIS database. The destruction (by erosion, by flood, etc.) of the tell settlements can be monitored virtually from one day to the other. In addition to a precise site condition assessment, the project yielded fresh information about settlement layouts, such as the presence of enclosures. At some sites, aerial photography was followed by a magnetometer survey.
