This large structure was located to the south west of the remains of the church of St. Martin-Le-Grand and, significantly, very close to the south west corner of the Saxon church (S14). The structure mainly consisted of a substantial area of orange-brown clay, sub-rectangular in plan and on an east-west axis. There were also three post holes, 37 stake holes representing internal divisions and a beam slot. Its minimum internal dimensions are 10.25m (E-W) by 4.17m (N-S). The structure and overlying soil deposits were eventually sealed by a metalled surface which dates to the 11th-12th century. (location accurate to the nearest 2m based on available information)
