Abstract
The Carlo's V Castle, located in Crotone Town, on the lonian coast of the Calabria Region (Italy), date back to the 13th century d.C. (Fig. 1). During its long life, the building changed several owners and Sustained the damages and the consequent reconstructions due to the innumerable naval battles. Moreover, the castle Suffered the action of the earthquakes which always afflict the region. With the principal aim of detecting the location, depth and geometry of the rests of destroyed structures, a systematic Ground Penetrating Radar (GPR) Survey was carried out in the area inside the boundary Walls. The results are sixty-two one-meter-spaced, filtered and migrated radargrams arranged in four 3D data-sets. From each data-set, the most significant time-slice was extracted. To reduce the ambiguity in the GPR data interpretation, additional geophysical techniques, Such as Magnetic (M), and Electrical Resistivity Tomography (ERT), were carried Out with a partial superimposition with the GPR data. A comparison and a joint interpretation amongst different geophysical data pointed Out Some very remarkable features associated to buried remains and possible buried cannonballs. With the secondary aim to check the presence of an old military walkway linking two bastions a GPR profile was carried Out Oil the sea side boundary wall. The GPR results are in agreement with in ERT Survey carried Out Oil the same profile and consistent with the presence Of all underground passage.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
