Geophysical investigations, including a measured topographical survey of the castle earthworks using Differential GPS and EDM, geophysical investigations – Earth resistance, ground penetrating radar and gradiometer surveys. The investigation focussed on the main earthworks of the castle motte, the inner bailey and the outer bailey. Anomalies were revealed which may relate to buried archaeological remains. The work was carried out by Nottingham University and Birmingham University as part of a research and training exercise the objective being to create a digital record of the surface and subsurface remains at the site using non-intrusive techniques. The topographical survey was carried out to investigate earth works surrounding and at the castle, the geophysical survey intended to provide information regarding the extent and preservation of any subsurface archaeological remains.
