Verification of Geophysical Surveys by New Archaeological Excavations on the Grounds of the Middle La Tène Site of Němčice in 2021–2022

important archaeological sites in Moravia. Non-destructive archaeological surveys including a largescale magnetometer survey, field artefact collections, and metal detector surveys have been carried
out there repeatedly over the past two decades. New archaeological excavations during a new project
were focused on selected areas and situations identified during magnetometer prospection. The results
of an archaeological investigation of the site using test pits confirmed settlement, glass-making and
ritual activity under magnetic anomalies at the site. The new possibility of comparing uncovered
sunken features and distributions of magnetic anomalies provided new feedback for a more precise
interpretation of similar anomalies from magnetograms. An additional detailed apparent magnetic
susceptibility measurement in situ showed another possibility for the application of the geophysical
method during archaeological excavations. We were able to obtain additional information about the
fills or possible post-depositional processes of various sunken features in the case of vertical profiles
monitored by magnetic susceptibility meter measurements. The use and combination of various
geophysical data has been beneficial in the case of an archaeological site as important as Němčice, and
will continue to be so in future archaeological research of the site.
