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 on archaeological site recognition, delineating buried structures, and help on excavating strategies. The first geophysical methods used in Portugal were geoelectrical methods followed by magnetic methods; today those two methods are still used; however, georadar and electrical resistivity tomography have also been used on a routine basis whenever the local conditions allow their use. Four archaeological sites will be described as examples on the use of geophysical methods in Archaeology. Two of them are from roman times (the Roman Villa of Tourega, in central Portugal and the Roman town of Troia, in the west coast of Portugal), one is from Neolithic times (a burial mound in central Portugal); the last one is a recent archaeological site (eighteenth century) and has to do with the location of a crypt known to exist in the garden of the Portuguese Legislature in Lisbon. Only electrical resistivity tomography and georadar were used. The sites were chosen because in all of them there were already previously excavated areas or there were plans for future excavation. When choosing those sites the idea was to be able to compare the interpretations of the geophysical data with the results of the excavations.
