The Keeills Research Project, in conjunction with BACAS, carried out geophysical surveys aimed at detecting and characterising subsoil features associated with Keeill Bow, an Early Christian Chapel.
Little Bredy 2012 Observations of Possible Megalithic Structures in the Valley of Stones, Little Bredy, DorsetJohn Oswin
The purpose of this report is draw attention to some stone assemblages, which may be worthy of detailed survey, and be found to be man-made rather than natural. The Valley of Stones and its environs also contain particularly fine groups of ‘Celtic’ prehistoric fields
Lansdown 2018 Little Down Field, Upper Farm, Upper Langridge, BathJohn Oswin, Janet Pryke and Robin Holley
In March 2018, BACAS undertook a geophysical survey of extant earthworks known as the ‘Romano-British Settlement’ in a triangle shaped field to the east of Sir Bevil Grenville’s Monument. This site is a scheduled monument, Site No. 1004527. Several anomalies of an archaeological origin are clearly visible. Cut features such as banks, ditches, walls and structural features have been identified on the ground and in both the resistance and gradiometer data.
Laverton 2018 Laverton, Somerset, Field east of the Piggery, Geophysical Survey, December 2018John Oswin
The surveyed area showed a round feature some 20 m across, possibly all that remains of a barrow, with a short linear feature to the west of it. These were just within the southern edge of the plot, so there may be further archaeological detail just to the south. Nearer to the eastern edge is a large ditched enclosure with a right angle corner but with a wavy western side and with a probable entrance to the north. At the entrance, the western ditch terminated in a large pit. There are signs of an eastern side to this enclosure, but the geophysics on this side is indistinct. There is no direct dating evidence for this enclosure, but the entrance seems to point at the massive Peart Villa (surveyed in 2003 – 2004), 1 km to the north, and this may imply a Roman origin. There are also signs of numerous pits within the survey area.
Laverton 2009 Geophysical survey in Laverton Churchyard, 2008 – 2009John Oswin and Philip Day
This work continued from a geophysical survey conducted in 2006, which possibly showed a building in the southern portion of the churchyard. There is some sort of stone structure under the southern portion of the churchyard, but it is unlikely to be a dwelling or earlier church
Little Chalfield 2017 Little Chalfield LawnsRob Arkell
Resistance and magnetometry surveys were carried out in the grounds of Little Chalfield Manor to look for evidence of earlier medieval buildings. The magnetometry survey revealed a portion of a circular feature twenty metres in diameter. A trench through the feature discovered a ditch containing bronze age pottery in the ditch fill. This suggests the feature is the remains of a ploughed out round barrow similar to others in the vicinity. The resistivity survey did not show any linear high resistance features which could be interpreted as walls but one pattern of low resistance was investigated. A trench across the feature contained demolition rubble (mortar, plaster, window glass and building stone fragments) which indicated that a building, thought to be the medieval manor which was demolished in 1830, had stood nearby.

Nether Compton 2011 The Nether Compton Roman coin hoard in its archaeological contextJohn Oswin
A hoard of some 22,500 Roman coins was unearthed in Nether Compton parish in Dorset by a member of the Yeovil Metal Detector Club in 1989. It remained in Dorset County Museum without the resources to study it for a number of years before it was retrieved, broken up and sold, so it was never fully analysed. There was no indication of archaeological remains in the field where it was found, although there were unsubstantiated rumours of there being a Roman villa in the field to the west. A geophysical survey was carried out by BACAS and this indicated significant Roman and possible pre-Roman activity in the fields
Peart 2007 Peart Roman VillaJohn Oswin
The presence of Roman structures in the area between Peart Woods and Chatley was known to the Revd. John Skinner in the 1820s. Fieldwork by John Prescott in the 1980s had shown pottery scatters in the area. In October 2003, BACAS carried out a geophysical survey. Trial excavations were carried out in April and May 2004
Prior Park 2018 Monument Field, Prior Park, BathTim Lunt
Monument Field at Prior Park is named for Ralph Allen’s Monument, built circa 1766 by Bishop Warburton following Allen’s death, which was demolished due to its dangerous condition in 1953. An earlier Gothic Lodge on the same site from the 16th century or earlier seems to have formed part of the later Monument. In addition the Wansdyke, dug circa 6th century, possibly crossed the field. Geophysical survey has confirmed that there is stonework probably related to the Monument and Lodge structures in an area which relates to the mapped position. A bank and ditch which may be the Wansdyke also exists as shown on the 1939 map.
Priston 2017 Priston – Pensdown, March 2017John Oswin and John Richards
Geophysical survey was conducted in March 2017 in pursuit of Roman structures on the southern slopes and approach to Pensdown Hill, Priston
Priston 2016 Geophysics at Priston 2015 and 2016John Oswin
A survey of Goosemead, to the north of already-surveyed Town Hill, had to be abandoned in 2015 when vital equipment failed. It did not prove possible to return to the field because of incompatible agricultural use. A survey in 2016 concentrated on Inland, a triangular paddock to the south-west of Town Hill, immediately across a lane from that field. This showed significant activity, including half of a sub-circular enclosure at its western end.
Priston 2014 Geophysical Survey on Town Hill, Priston, Somerset, 2014John Oswin
An area of approximately 4 ha was subject to geophysical survey in the field called Town Hill in Priston parish, just to the west of the village. The survey indicated a field system of curving ditches on the far west of the field, probably extending under the Marksbury lane, which is probably prehistoric in date, also with a possible round house at the south end of the survey, on the plateau. Towards the north end of the field, at the bottom of the north-facing slope, there were signs of activity around an earlier stream path. In the far north-east of the field there were signs of a substantial structure, which probably extended north into Goose Mead and east under Mill Lane.
Priston 2008 Geophysical Survey at PristonJayne Lawes
BACAS conducted a combined Geophysical Survey of the field known as Great Barn Close at Priston at the request of Priston Millennium Committee in October to November 2007. The survey was requested as part of a wider study of the Parish and because of the find of a Roman burial in the field in 1917. This report includes some of the information from Wedlake’s excavations as well as combining surveys of the field
Roman Baths, Bath 2018 The Roman Baths, Bath, Archway Project, Geophysical Survey, January 2018John Oswin
The geophysical survey was undertaken as the first part of archaeological work in the vaults to the south of the Great Bath in the Roman Baths at Bath. There were two areas under the vaults to be surveyed, and these were separated by a single wall. Twin-probe resistance survey, where possible, and resistivity profiles were carried out. Resistivity profiles to a depth of 2 m proved the most useful technique. Most features were observed at approximately 1 m depth. These included a number of probable drains running to the centre line of the area. Between this central line and the wall of the Great Bath, there was another substantial feature from 1 m depth downwards, midway along this area, not previously identified. Other techniques tried included thermal imaging and ground-penetrating radar.
Royal Crescent 2014 Areas near the Royal Crescent, Bath: A report on geophysics surveys by BACAS, September and December 2013Janet Pryke and John Oswin
The lawn below the Royal Crescent Ha-ha in Bath had been the site of a geophysics investigation in 2012 by BACAS. This project has been extended and added to by this work making further surveys in areas near the Royal Crescent
Royal Crescent 2013 The lawn below the Royal Crescent Ha-ha, Bath: A report on geophysical surveys by BACAS, June and October 2012Janet Pryke and John Oswin
The lawn below the Royal Crescent Ha-ha in Bath was part of an archaeological investigation in 2002 for a Time Team television programme on Channel 4. In this they confirmed the route of and excavated a known Roman road down across this lawn, and also excavated nearby burials. They also revealed and excavated a Late Bronze Age ditch. This project extends the geophysics part of this work, and demonstrated that the Late Bronze Age ditch is extended to an enclosure. This work also investigated a large ditch-like formation running from NE towards the SW across the lawn, and other features including an area with pit-like chambers below the ground.
