Archaeological Geophysics in Portugal: Some Survey Examples

The first attempts to apply geophysical methods to archaeological sites in Portugal date from the mid-sixties of the last century. Since then, geophysical methods have been used more and more frequently to help with archaeological site recognition, delineating buried structures, and help with excavating strategies. The first geophysical methods used in Portugal were geoelectrical methods followed by magnetic methods. Today these two methods are still used but the georadar and the electrical resistivity tomography methods have also been used on a routine basis whenever local conditions permit.
