3D LiDAR model of Eildon Hill an Iron Age hillfort in Melrose, Scotland. The digital terrain model offers a view of the surrounding landscape without obstruction from foliage. Eildon Hill reaches 422 metres high and covers an area of around 162,000 square metres making it one of the largest hillforts known in Scotland. Hillforts were settlements constructed on natural hills, typically fortified with earthworks around the contours of the hill. They were widely constructed across Britain and Ireland in the centuries preceding the Roman conquest of the regions. Excavations have revealed evidence that the hill fort was occupied from 1000 BCE, in the Bronze Age. Image contains UK public sector information licensed under the Open Government Licence v3.0.
