A Survey at Tilgate Forest Lodge (Found website April 20th 2004)
Over two weekends in February and March, we carried out a survey of some earthworks at Tilgate Forest Lodge, between Handcross and Pease Pottage. The earthworks had been discovered whilst clearing woodland, and comprised a series of earthen banks, which could be traced for some distance across the property. We initially carried out a survey of the visible earthworks, planning them onto a map and recording sections across them with a level. They comprised a set of three parallel banks up to a metre high with shallow flanking ditches, running south-west to north-east, which could be traced for about 150 metres through cleared woodland. At the southwest end they could be seen as parch marks on the ground and from an aerial photograph extending for a further 100m, although they did not exist as visible earthworks. Here they appeared to end on meeting an earthwork running east-west, marked as a track on the 1910 OS map. At the north-east end they disappeared in a ploughed field, to reappear in a further piece of woodland, where they were traced as a single bank and ditches for a further 100m. Other banks were recorded running north-west to south-east in this woodland, and could also be traced to the south-east running into another section of woodland.
The main set of banks then disappeared again under a grass field to reappear in more woodland. Here they could be traced, as a complete set of three banks and ditches, meeting another track boundary bank, and then running off to the north-east down slope into a stream valley. On the slope the flanking banks peter out, with the central bank continuing down to the stream where it meets other banks running parallel to the stream and appearing to enclose part of the streamside. Other possible earthworks could be seen in the stream valley. Overall the banks could be traced for about one kilometre.
A one metre wide section was excavated through one of the banks in an effort to date it and record its profile. It comprised a bank of sandy clay dumped onto the natural soil with shallow flanking ditches on either side. There was no remnant land surface below it. The only find was a single prehistoric flint flake from underneath the bank.
The ploughed field mentioned above was fieldwalked during the first weekend. This produced a small quantity of pottery, mostly Medieval and Post Medieval, and some prehistoric flintwork. The flintwork can be dated from the Mesolithic to the Bronze Age, and included a very rare polished barbed and tanged arrowhead. A local collector has picked up microliths, leaf shaped arrowheads and an ordinary barbed and tanged arrowhead, confirming prehistoric activity from the Mesolithic to Early Bronze Age.
These earthworks are not easy to date. Old maps dating from 1724 show the whole area to be woodland, which has been progressively cleared in the late 19th and 20th centuries. The field boundary adjacent to the largest set of earthworks respects their alignment so must postdate them, whilst in other areas of now cleared woodland the banks have been removed so must predate the woodland. It therefore seems likely that they could be Medieval boundary ditches. Near the stream, it is possible that the earthworks are part of a water management system possibly associated with ironworking, although we could find no evidence of actual ironworking. I would like to thank all those members who took part in the survey and excavation, and the owners of Tilgate Forest lodge, Mr & Mrs Mortimor. Mark Taylor, the County Archaeologist, initially suggested that we carry out the survey. A full report will be produced in due course.
