Mid-late Bronze Age pottery, possible prehistoric enclosures and field systems were found to the west of Blind Lane in 1997 prior to Channel Tunnel Rail Link works. Curvilinear ditches and slots may represent two prehistoric enclosures. Linear ditches spread more evenly across the site may indicate the survival of one or more field systems. A largely complete bucket urn may be related to the Deverel Rimbury tradition of the mid 2nd millenium BC. Some of the pottery sherds may be early 1st millenium BC in date. There appears to have been a contraction of settlement in the early 1st millenium BC.
