  • Descrição: In this paper, we present the results of non-destructive integrated geophysical surveys (ground penetrating radar (GPR) and seismic sonic) performed in the crypt of the Basilica of St Nicholas in Bari, Italy. The aim was twofold, namely to investigate the consistency of restoration work performed in 1950 and the presence of features of archaeological interest. The GPR technique has also been exploited to characterize the subsurface water content under the crypt. In particular, the existence of buried anomalies, probably due to the restoration work, has been identified. Moreover, by means of an electromagnetic-wave velocity analysis, an estimation of the volumetric water content under the floor has been achieved. The results indicate the main causes of the deterioration and have provided significant information for the safeguard of this historical building. Furthermore, the GPR survey allowed us to identify some anomalies buried under the crypt that are probably of archaeological interest. Finally, both sonic tomography and a GPR survey have been performed on an important mosaic, and have enabled us to identify probable 'internal' reasons for its decay.
