Trial trenched evaluation in 2007 revealed a number of prehistoric, Roman and post-medieval ditches, on three different alignments, and appear to represent fragments of three distinct landscapes.

The Iron Age landscape was overlaid by a second field system consisting of ditches aligned slightly west of north to south. Dated material from these ditches is Roman. This Roman, or possibly late Iron Age, realignment of the landscape is paralleled at the Garrison, for instance on Area 2 where the Middle Iron Age round-house was crossed by a Roman drove way aligned N to S (MCC2868). There is good reason to associate this Roman-period reorganisation of the landscape with the early years of the oppidum of Camulodunum, one of the defensive lines of which (Berechurch Dyke) runs along the edge of Area S2 (south).

Later, a third field system is evidenced by a series of ditches containing peg-tile and post-medieval glass. This field system may well have been created in the medieval period, but the presence of recent bottle glass shows that it continued in use in the post-medieval period.<1>
