One of two medieval robber trenches (with MCC3005) which had completely robbed-out two parallel east-west orientated Roman walls from the Roman Circus MCC2805 (although not fully realised at the time of excavation).

This robber trench was located on the second, smaller southern wall of the Roman structure, 4.4m to the south of the north wall and approximately 0.7m wide. Both walls had been completely robbed-out by the medieval robber trenches (although there was no suggestion that the original foundation trenches had been widened during the robbing). The remains of some Roman structural material (greensand stone, flint, septaria and Roman coursing tile) was found within the backfill of the robber trenches.<1>
