These models are from archaeological excavations at Hartygrove Break, Lower Hazel, South Gloucestershire by the Southwest Anarchy Research Project (SWARP), University of Bristol, aimed at determining the extent and respective dates of the building complex that has been previously identified and excavated by a team of archaeological volunteers known as the Thornbury Archaeology Group (TAG) in association with Thornbury Museum. The Thornbury Archaeology Group began their excavations in 2011 under the expert guidance of archaeologist Roger Howell with the full support of the landowner, John Wilson-Smith.
