3D LiDAR scan of Caesars Camp, an Iron Age hillfort in Berkshire, UK. The digital terrain model offers a view of the surrounding landscape without obstruction from foliage. Hillforts were settlements constructed on natural hills, typically fortified with earthworks around the contours of the hill. They were widely constructed across Europe, Britain and Ireland in the centuries preceding the Roman conquest of the regions. Caesars Castle is an unusually-shaped hillfort enclosing an area of around 70,000 square metres, making it one of the largest in the region. Despite its name it was constructed centuries before Julius Caesars invasion of Britain in 55 BCE. Image contains UK public sector information licensed under the Open Government Licence v3.0.
