Archaeologists in the Czech Republic are utilizing advanced remote sensing technologies, including aerial survey, magnetometry, and airborne laser scanning, to uncover thousands of hidden Neolithic archaeological sites, many of which are 5,000-year-old burial mounds. These ancient structures, known as long barrows, are often invisible to the naked eye but are now being revealed by subtle landscape differences highlighted by technology. The research, led by the Institute of Archaeology at the University of Wroclaw and collaborating universities, has identified approximately 2,900 features, including burial mounds and associated settlement areas, providing new insights into prehistoric funerary practices and land-use strategies. The findings confirm that these long barrows were deliberately constructed at the margins of settlements, creating a spatial separation between the living and the dead that was maintained for millennia.
