Remarks on the research methods of the Neolithic circular enclosures: possibilities and limitations of non-invasive investigations in the light of the research of the Ligetfalva, Gesztenyési-dűlő site

This study presents the non-invasive investigation of a Late Neolithic circular enclosure discovered not long ago. We were able to document traces of a settlement and the nearly complete layout of a treble circular enclosure system (roundel) from the Lengyel culture at Ligetfalva, Gesztenyés-dűlő in Zala County. We provide a review of the possibilities and limitations of non-invasive research methods regarding Neolithic circular enclosures by presenting the investigations of the roundel at Ligetfalva conducted by land survey, aerial photography and geophysical survey.
