The aim of this paper is the study of the paintings on architectural elements in the mediaeval crypt of the 'Santo Sepolcro' (Holy Sepulchre) in the Cathedral of Acquapendente (Northen Lazio, Italy). The scientific approach has been developed through the mapping of the traces of original painting still visible on the architectural elements of the crypt. The mapping was done by analysing the paint pigments and binders still preserved in small fragments on the architecture of the crypt. Then painting samples were taken for laboratory analysis aimed at identifying the composition of pigments and binders. These samples were examined through micro-stratigraphic analysis, Fourier transform infrared spectroscopy and X-ray fluorescence spectroscopy. To reach the established goal, in situ documentation was performed by visible and ultraviolet fluorescence photogrammetry. In order to obtain a reconstructive three-dimensional model of the architectural elements with colours as much similar as possible to the originals, the obtained model was rendered using the colour palette gathered by the scientific analyses.
