Title
New perspectives to save cultural heritage

archaeological structures are often superimposed. Besides the
strong signal connected to the anchorages of the vineyard and
the diffused background noise caused by the presence of sparse
offending magnetic items rendered the correct visualization of
the buried archaeological sources more difficult.
3.3 Santomola (Italy)
The third magnetic survey was executed in a military zone.
During some channeling works a few tombs belonging to a
necropolis of the V-1I century B.C. were revealed. The tombs
were dug inside a compact and well cemented grainstone and
some of them have also a counterfosse. The thickness of the
ground of coverage never overcomes 0.5 m. The archaeologists
of the Archaeological Superintendence of Apulia had only a
limited time to access the site and to effect systematic studies.
Therefore to better define the extension of the necropolis and
guide some aimed excavations a geophysical investigation was
undertaken. The total surface of the surveyed area was notably
influenced by the presence of metallic enclosures and a large
fuel silo buried in the ground. Notwithstanding all the possible
precautions, the effect of this last source of intense magnetic
noise is evident in Figure 6, in the southern part of
magnetogram 2.
Figure 6. Surveyed area in Santomola. The strong magnetic
signal visible in the magnetogram 2 represent the effect of a big
fuel silo buried in the ground. The spot localized anomalies are
connected to the presence of the graves.
Figure 7. The black line in a) and b) represents the limit of the digs executed in the areas 1 and 2 of Figure 6. The recovered tombs
are well shown in c) and d). The good correspondence between the position of the tombs and the magnetic anomalies appears very
clear.
