The article examines the possibilities of non-invasive survey of a paper architectural model using computed tomography. It is based on interdisciplinary collaboration between the Prague City Museum and the Institute of Theoretical and Applied Mechanics of the Czech Academy of Sciences. On selected parts of the so called Langweil’s Model of Prague, it presents the possibilities of using this method in the exploration of the intricate internal structure and material diversity. The conclusions are assessed in the context of historical methods of creation and the current preventive care. The survey also involves collecting selected samples and analyzing them using X-ray fluorescence spectrometry (XRF) and Fourier-transform infrared spectroscopy (FTIR). The introduction deals with the description and history of the selected parts of the model from the collection of the Prague City Museum that were surveyed. It also briefly describes and evaluates the restoration process of this model which was conducted between 1962 and 1969. It also addresses the current situation regarding the re-display of the model, the reconstruction of the main building of the Prague City Museum, and the possibilities of extending the current investigation to other parts of Langweil’s model. It concludes that computed tomography provides a very precise image of the physical condition of the museum object and complements well with investigation using XRF and FTIR.
