This contribution reports the documentation of the conservation status and the pictorial technique of a wall painting and a stucco arch at Palazzo Nuzzi in Orte, central Italy (Viterbo district), achieved using a wide combination of non-invasive and micro-invasive diagnostic techniques. Specifically, a photogrammetric approach has been used for 2D and 3D ultraviolet fluorescence (UVF) acquisitions. Moreover, the conservation status of the wall painting has been also investigated by a non-invasive active infrared thermograghy technique, i.e. Pulse Compression Thermography (PuCT), used here for the first time on a wall painting to map the surface and sub-surface cracks in the first layers. Pigments, grounds and organic binders were characterised by X-ray fluorescence spectroscopy, micro-stratigraphic analysis, Fourier transform infrared spectroscopy and gas chromatography coupled with mass spectrometry. The results of this unique combination of advanced tools corroborated the historical-artistic attribution to the school of the architect Andrea Pozzo
