Mapping a new-found iron age hillfort (castro) by integrating airborne lidar data and gpr prospection
| Resumo: | The application of LIDAR (Light Detection and Ranging) technology has revolutionized archaeological research, offering unprecedented insights into past cultural landscapes and site analysis, sometimes revealing monumental architectures and settlement systems totally unknown before. In this study we present the use of airborne LIDAR data in uncovering an unknown Iron age hillfort, located in NW Portugal (Ponte de Lima municipality), in a densely vegetated hilltop. By using high-resolution LiDAR data, researchers identified and mapped the topographical features indicative of the hillfort, which had remained concealed beneath dense vegetation, in a spur. The LiDAR analysis revealed distinct structural elements of the defensive structure, and possible habitation areas, and provided a detailed topographical map that guided subsequent ground verification. The subsequent field inspection enabled the confirmation of the LIDAR data, being identified alignments consistent with presence of a defensive system, and platforms from possible residential areas. Some scattered iron age ceramic fragments were also found, further corroborating ancient human activity. Furthermore, a GPR prospection confirmed the presence of buried archaeological features. In spite of the dense vegetation GSSI GPR System (sir3000), with 400MHz antennae was used. Several profiles were acquired over the supposed defensive system and habitational area. The profiles interpretation showed reflections patterns that are consistent with the presence of a stone wall, and possible buildings. These non-invasive methods proved invaluable in detecting the hillfort, its spatial organization and extent, significantly contributing to the understanding of Iron Age settlement patterns in the Iberian NW. The findings underscore the potential of LiDAR in archaeological discovery and heritage preservation, illustrating its effectiveness in remote sensing and landscape archaeology. |
