3D LiDAR model of Danebury Camp, an Iron Age hillfort in Hampshire, 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 Britain and Ireland in the centuries preceding the Roman conquest of the regions. Evidence found suggests that the fort was built 2500 years ago and occupied for nearly 500 years until the arrival of the Romans.
