To enhance the knowledge of the unexcavated portions of the archaeological site and to locate the position of the unknown buried structures, geophysical prospections employing the Ground Penetrating Radar method were performed between September and November 2017. For the measurements, a GPR system SIR3000 (GSSI), equipped with a 400 MHz bistatic antenna with constant offset was employed to survey 18 different sectors closing to few excavated area. Taking into account the environmental conditions of the site and the nature of the hypothesized structures, some areas have been surveyed with a spacing interval between parallel profiles of 0.25 m while other areas have been investigated with a spatial interval between closed parallel profiles of 0.50 m. Furthermore, differential magnetic surveys were carried out using the Geoscan FM256 in two areas, overlapping the GPR areas. With the aim to have a better understanding of the subsurface, a qualitative and quantitative integration of the results, have been employed. For the integration process the following techniques: maps overlays and RGB colour composites (graphical integration), binary data analysis and cluster analysis (discrete data integration) and data sum, data product and principal component analysis (continuous data integration) have been used. The results obtained from the geophysical surveys were interpreted together with the archaeologists to define the meaning of the individuated structures and to enhance the knowledge of the ancient town's layout and mapping.

In this contribution we will show the combination of different migration results calculated on the same Bscan. This allows to account for the variation of the propagation velocity in the soil below the measurement line. Horizontal and vertical variations of the propagation velocities will be considered. A validation vs. real data will be provided, in a case where reinforced concrete was tested.

In the last decade portable devices for analyzes on Cultural Heritage (e.g. laser-scanners, spectroscopes, XRF) has reached levels of reliability such as to be able to replace benchtop instrumentation for survey in situ. One of the most effective application of these devices concerns the digitization and the diagnosis of artworks preserved inside museums. Indeed, moving art objects or finds from its place of preservation to specific laboratories can often result difficult due to several reasons as fragility, big sizes, risk of damage, lack of authorizations etc. The paper shows the results of a collaboration between the IPCF-CNR of Messina and the Archaeological Museum of Lipari aimed at the creation of a mobile laboratory for chemical analysis and 3D digitizing of finds presenting different issues. The activities have been carried out using two performing and contactless tools: a laser-scanner arm by Faro (sometimes in combination with an external camera) and a handheld Raman spectrometer by Brucker.

The Santa Caterina tower in Nardò (Lecce, Italy) represents one of the many types of coastal towers of the ancient Terra d'Otranto province. It was part of the defensive system of the Ionian coast of Salento against the Turkish threat. The integrated geophysical prospections are part of the analysis of the tower about constructive elements, wall discontinuities, functional modification in order to understand the phases and the change of the structure over the centuries. The information collected will be useful for a restoration project finalized to recover a building abandoned for years.

In this paper the results of a GPR prospecting performed in the cathedral of Acerenza (Basilicata, southern Italy) are proposed. The investigation was aimed in particular to search, if any, traces of the tomb of St. Canio with his bones, protector of the town of Acerenza. Data processed with GPRslice code have been 3D shaped to define the position, depth and volume of the tomb. The results are also in agreement with the historical sources that indicate the probably burial place.
