ABSTRACT

The Maqsura and its Mihrab is one of the most outstanding locations of the Mosque-Cathedral of Cordoba built during the reign of Caliph Al-Hackam II (962-965 AD). The ART4ART mobile laboratory has allowed to study materials, state of conservation and structure characteristics at Maqsura without sampling. 3D digitization, elementary and molecular physicochemical analysis, Laser Doppler Vibrometer (LDV) and Ground Penetration Radar (GPR) were employed to study mosaics, mural paintings roof and subsoil. 3D digitization using photogrammetry offers the possibility to digitally manipulate the models and observe small details on the surface, but also to analyze the monument degradation in time, by subsequent 3D models of the same areas. GPR and LDV techniques are noninvasive methods to investigate internal structure of the walls or their state of preservation (cracks, detachments). Chemical analysis was used for material identification in situ.

This multidisciplinary approach based on non-destructives techniques allows us to study Maqsura materials and its state of conservation in situ and real-time without sampling assay, what makes this approach as a good protocol for the diagnosis of the Cultural Heritage.
