Archaeology was commissioned by Videotext Communications Ltd to carry out archaeological recording and post-excavation analysis on an evaluation at Coberley Villa in Gloucestershire (centred on NGR 396750 215200) as part of the ‘Time Team’ television series. Eleven trenches were excavated to investigate the extent, character and condition of the Coberley villa remains. The trenches targeted a mosaic pavement discovered by metal detectorists in 2003 and structural remains indicated by geophysical surveying to exist in the vicinity of the mosaic. The remains of a demolished villa were recorded which appeared to have been H- shaped in plan. The evidence suggests that the north and south wings were possibly later additions to an original structure. The mosaic pavement appeared to be within a triclinium. The central panel had been removed, possibly evidence of Christian iconoclastic destruction. Dating evidence from the Site suggests that the villa was constructed in the 2nd century AD; the mosaic is dated on stylistic grounds to the late 2nd to early 3rd century. There is no firm evidence for the abandonment of the villa, but the presence of a little 4th century pottery, and several mid to late 4th century coins, indicates use of the Site well into the late Roman period, although all this evidence comes from post- demolition contexts. Geophysics also located evidence of industrial activity on the Site. One of the geophysical anomalies was excavated and transpired to be a partly demolished kiln, the stone-built, subterranean element of which was still preserved in situ. The kiln was probably producing roof tile for the villa construction. iii Coberley Villa, Gloucestershire Archaeological Evaluation and Assessment of Results Acknowledgements This programme of post-excavation and assessment work was commissioned and funded by Videotext Communications Ltd, and Wessex Archaeology would like to thank the staff at Videotext, and in particular Michael Douglas (Series Editor), Melinda Corkery (Production Manager), Jim Mower (Assistant Producer), Jon Willers (Researcher) and Jenny James (Production Coordinator) for their considerable help during the recording and post-excavation work. The excavation strategy was conducted by Neil Holbrook and undertaken by Time Team’s retained archaeologists, Phil Harding (Wessex Archaeology), Brigid Gallagher, Ian Powlesland, Matt Williams, Raksha Dave and Tracy Smith, assisted by Paul Nichols, Richard Macpherson Barrett, Ed Stratford, Briege Williams and Nick Witchel of Gloucestershire County Council Archaeology Service. They were aided by local metal detectorists David Hutton and Don Sherratt. The geophysical survey was undertaken by John Gater, Fiona Chester and Mark Harrison of GSB Prospection Ltd. The field survey was undertaken by Henry Chapman (University of Birmingham). The excavation strategy was devised by Neil Holbrook (Cotswold Archeology). The on-site recording was co-ordinated by Jon Milward, and on-site finds processing was carried out by Laura
