We consider as a necessity existence of a centralized database that also includes ruin-monuments or monuments which are less known even by specialists. For each of them a team has traveled to mark with the help of a GPS device the location of each ecclesiastical monument belonging to the fortified churches in the southern Transylvania. These data will be correlated to the known data, to the bibliography of the monument, to the objects / items still owned by the particular monument, or to the information deposited in the Lutheran churches of Sibiu, Cristian, Mediaş or Biertan. Our goal, in the end, it is that all data must be easy to get to, available in real time and permit an unproblematic identification of the site by non-specialists.
