3D LiDAR scan of Thornborough Henges, an ancient monument in North Yorkshire, UK. The digital terrain model offers a view of the surrounding landscape without obstruction from foliage. This is a unique cluster of Neolithic monuments that lies on a raised plateau above the river Ure. The three huge circular henges ??sometimes described as the Stonehenge of the North ??were built here about 4,500 years ago over an earlier monument. The site includes many large ancient structures including a cursus, henges, burial grounds and settlements. Image contains UK public sector information licensed under the Open Government Licence v3.0.
