Test trenching by D Graham of SyAS confirmed that the low platform visible just outside and slightly to the north of the postern gate of Farnham Castle is in fact a laid gravel surface. The feature was first noted during a landscape survey in 1998 and appears to lie at the western end of a slight flattened bank that runs through the Park more or less parallel to the existing Avenue. Previous work had shown that this bank appeared to be a gravelled road with side ditches and to date to the mid 17th century. The current work confirmed the likely date of the feature, with the recovery of a lead pistol ball, a number of coiled lead strips and a quantity of clay pipe stems of probable 17th century date, seeming to point to the platform being the site of a Civil War cannon park. This formed part of the Parliamentary army base in Farnham Park and is known from documentary sources to have been sited close to the walls of the castle. The fact that the road and platform respected the northern edge of the medieval strip field system probably means that it follows the line of an earlier medieval trackway leading to the postern gate. Part of a pit containing medieval carved stonework was also located and this may represent building rubble from the restoration works carried out by Bishop Morley at the end of the Civil War.
