Clun Castle, Clun, Shropshire: Report on Geophysical Surveys, March 1998
Author(s): Neil Linford, Paul Linford, Andy Payne
Earth resistance, magnetic and Ground Penetrating Radar (GPR) surveys were conducted at Clun Castle, Clun, Shropshire, to demonstrate geophysical survey techniques for archaeological prospection as part of a Science Engineering and Technology week organised in March 1998. Due to the limited success and coverage of the survey the results were not formally reported at the time, but have been completed now following a recent request to include these in a wider publication of research at the site. The earth resistance survey (0.4 ha) suggests tentative evidence for some structural remains within both of the outer baileys covered with this technique, and there is some correlation with the magnetic results (0.3 ha) in the South East Bailey despite the presence of ferrous interference. Results from the trial GPR transects were of limited use due to the penetration depth of the higher centre frequency antenna used over the South East Bailey and the 2 m wide spacing between the parallel profiles. Some more useful results were obtained from the North East Bailey with a lower centre frequency antenna, although these could not confidently confirm the presence of structural remains.
