“Hidden” Landscape of Prehistoric Burial Monuments: The Use of Remote Sensing in the Detection of Neolithic Long Barrows in Bohemia (Czech Republic)

Abstract

Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long-term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated archaeological features in the intensively cultivated landscape of north-western Bohemia, Czech Republic. The analysis focuses on two long barrows near Mount Říp (Dušníky 1 and Nížebohy) and combines oblique aerial photography, magnetic survey and airborne laser scanning (ALS). The results demonstrate that even heavily levelled long barrows remain detectable through the complementary use of non-invasive methods. ALS confirms the presence of subdued barrow mantles, while aerial imagery and magnetometry provide key information on monument layout, internal structure and associated burial features. In addition, the remote sensing data reveal further funerary monuments of later prehistoric periods, indicating long-term continuity of burial practices and the development of enduring ritual landscapes. Settlement activities are spatially restricted and clearly separated from funerary zones. This study highlights the value of multi-method remote sensing for reconstructing prehistoric burial landscapes in intensively cultivated regions.
