A Remotely Piloted Aircraft photogrammetric survey of the henge and its immediate landscape, August 2016. Part of a project to investigate an arc of large anomalies beneath the 4,500 year old bank of Durrington Walls, discovered by a Eurpean team led by Professor Vince Gaffney of Bradford University who have been carrying out a series of geophysical surveys over a large part of the Stonehenge landscape. The excavation involves the combined forces of the Stonehenge Riverside Project, the Hidden Landscapes team and the National Trust.
Prior to the aerial survey being carried out, permissions were obtained from the MOD, as Durrington Walls and just about all of the Stonehenge landscape is within Danger Areas with regular low flying routes. Also Land owners and gaurdians such as the National Trust and English Heritage, had to give permission.
