3D survey for conservation: The case of the Caleo farmhouse in Campi Flegrei

The farmhouses of Campi Flegrei represent a unique heritage, which is marked by complex relevancies, con-sisting of territorial, archaeological, historical and constructive values. In fact, the farmhouses had grown in time over the ancient roman structures of the villae rusticae with a clear continuity of building techniques. Today, many of these farmhouses are marked by a condition of neglect. This, on one hand, has preserved their authenticity but on the other it has exposed them to the risk of loss and alteration of their values, especially concerning their constructive techniques and materials. In order to protect them, only a thorough survey and a 3D representation can help by managing the difficult strategies of conservation, like the one carried out on the «Masseria Caleo» in Pozzuoli, which stands out as a significant case-study, for the presence of a roman col-umbarium and for its belonging to the religious property of the monastery of S. Martino.
