Battisti 10, 1 Introduction The recent developments in automatic surveys and computerised graphics allow us to deal with some of the structural problems of ancient buildings far more accurately and with a greater wealth of details. Foundation subsidence, out of plan columns and vertical walls as well as surface irregularities can be better analysed and interpreted from a structural point of view if studied by 3-D visualisation techniques whose greater correspondence to the real object eliminates any possible simplification or rough estimation. In the present work advanced techniques for topographical survey and 3-D visualisation techniques have been used in order to create a 3-D model of the church of St. Salvator
