Confusion resolved after further study of RPP's plans and data - this was not recorded in the Roman phase of RPP's 2012 excavation because it is a medieval wall (10024) forming part of the church with 10045. Based on RPP's plan, this may be collapse of wall 10024, and not proper wall - hard to tell. The foundation trench for this wall cut through Roman layers, including the TSI stacks, which may have originally continued toward the S.
Alignment of large stones along south edge of trench going in to bulk wall which was not recorded by RPP. Remains unclear whether it is a wall.
