Evaluation by J Lowe of TVAS prior to submission of an application for redevelopment. The remains of the former manor (demolished in c 1988 following an earlier fire) were found to be in a relatively poor condition, with large areas apparently having been completely robbed and only fragmentary rubble remaining. Sufficient remains were encountered to establish the accuracy of known plans of the site however. The remains of the Elizabethan core of the building were particularly poorly represented.

As part of a continuing survey, directed by D Graham of SyAS, further work was carried out in the north-west of the park with the help of the Farnham Metal Detecting Club. This produced numbers of musket and pistol balls and case shot of various types. These probably relate to fighting in the park in 1643 during the Civil War.

Following on from work in 2002, a further area of the park was subject to a metal detector survey directed by D Graham of SyAS. A further scatter of shot, probably of Civil War date and of various types, was recovered and once again there were concentrations of finds in particular places.

Watching brief by G Pattison of SCAU and D and A Graham of SyAS during alterations. A number of burial vaults and inhumations were recorded below the church floor, most of which was lifted and re-laid. Evidence for the remains of a pre-12th century church was also recorded, in the form of wall footings and truncated floor deposits.

Soil-stripping, mapping and sample excavation by P Riccoboni of ASE on the site of the former Victorian mansion, following evaluation in 2004. The foundations of the structure were revealed to have been extensively robbed, although the cellars of the house had survived. No structural evidence for the preceding Elizabethan mansion that is known to have existed on the site was seen, although a single ditch containing 16th--17th century pottery was recorded beyond the footprint of the Victorian structure.

Final phase of the watching brief by R Lambert of SCAU, which commenced in 2007. No features of archaeological significance were recorded, but a number of worked flints of probable Bronze Age date, together with pottery and clay pipe stems of late 17th--early 18th century origin, were recovered

Continuation of evaluation and mitigation work by A Manning of WA during the construction of the A3 bypass. Mesolithic and Neolithic flintwork was identified at Hazel Grove Junction, and from peat deposits sampled at Boundless Copse, although the latter deposits were identified as Bronze Age in origin. Little evidence for Roman or Saxon activity was noted beyond the presence of a few Romano-British coins and pottery recovered near Thursley. Medieval features included field systems, hollow-ways and strip lynchets at Hammer Lane, Boundless Copse, Hazel Grove and Begley Farm.

Watching brief and resistivity survey by D Graham of SyAS during topsoil removal to create additional car parking spaces. The site lies outside the area of the former (now filled in) inner bailey ditch, and no features were detected. A number of finds were recovered during the topsoil removal, however, including a number of musket and pistol balls, and three powder caps from gunpowder flasks. An incursion of parliamentary forces into the castle courtyard occurred on 26 November 1642, with the royalist garrison surrendering as a result.

Watching brief by R Lambert of SCAU, following evaluation in 2006. No features of archaeological significance were recorded, but a number of worked flints of probable Bronze Age date, together with pottery and clay pipe stems of late 17th–early 18th century origin, were recovered.

Large-scale evaluation programme by A Manning of WA. Varied results were recorded, ranging from largely negative areas where no finds or features of archaeological interest were revealed, through to evidence for Neolithic activity, Bronze Age and Iron Age settlement, and post-medieval agricultural land management. Subsequent excavation revealed a significant number of pits, postholes and gullies of Late Bronze Age–Early Iron Age date.
