However, it is also possible that the medieval farmers utilized both the squarer "Roman" fields, and the older boundaries, merely dividing each small square field into strips, a pattern still visible within the area of Bunkers Park at the time of the Tithe Survey in 1840.(See map lower down.)By the time the Medieval Abbey of St.Recent archaeological discoveries along Westwick Row Leverstock Green, & Silverthorne Drive make it extremely likely that the cultivation of the land dates back to Iron Age times, and that at the very least, the two lanes were Iron Age track ways forming part of a well established Iron Age landscape in these parts.The finds of Iron Age as well as Roman material at Handpost Lodge Westwick Row, and in the garden of Silverthorne Drive provides a strong likely link between the two in both Chambersbury & Bunkers Lanes. Further study of the earlier Ordnance Survey maps where the still existent lines of field boundaries can be seen, shows the boundaries to be bisected by the known Roman Roads, and therefore predating the Roman period.The lanes themselves (prior to widening in places, particularly Chambersbury Lane) were also narrow and obviously predated the internal combustion engine.
The Handpost Lodge site indicates the likelihood of a Roman villa (i.e.Their relative age was, and still is in the case of Bunkers Lane, easily apparent to anyone walking or driving their length and seeing the extremely well established ancient hedgerows delineating the sides of the lanes.Additionally the lanes themselves show obvious signs of having been used for many centuries, as the road way has been down cut by continual usage in many places, leaving the fields on either side at a higher level than the road.A leaflet was circulated to all homes in the village to draw attention to the project, to encourage project suggestions and participation.When Bunkers Lane Open space, an area of about 50 hectares, (123½ acres) was acquired by Dacorum Borough Council for the use of the people of Dacorum at the end of 1995, it effectively secured a part of our local heritage.
