During the campaign 2018, our team has realized a superficial survey of a large extent in the site of Bufalareccia. This survey indicated the accumulations of significant artefacts in the area of site and also found out several superficial structures such as one well and three subterranean structures, possibly robbed tombs. Although the superficial survey will continue also in the following seasons, already now some information is needed, especially such as the overall chronology of the site. Based on similar experience made in Tarquinia, just the wells may be generally considered to be the archaeological situations, which are able to record the total or at least the partial chronology of a site. For this purpose, we would like to commence the archaeological excavation of the well, that is located in the sector G of the site. Since the sector G is the place of the highest density of the archaeological finds and because of earlier finds of painted acroteria indicating the hypothetical presence of the sanctuary here, we would like to organize in the sector G the magnetometric measurement, which could give us an imagination about possible presence of an architectonic relicts in this part, etc. For the same purposes, we would also like to perform the magnetometric measurement also in the area of sector C, where a site of a specific concentration of archaeological finds also occurs.
