English: Hadrian's Wall, Heddon on the Wall The wall ditch is on the right (north side), now shallow, beyond the level berm next to the wall. Excavations elsewhere suggest that this area may have had its own layer of defences such as sharpened stakes,at least where they were needed for defence. The outer courses of often triangular-shaped stones were in-filled with more random shaped and sized stones, possibly a more accurate restoration than seen elsewhere along the Roman Wall. The vallum can be seen in the field to the left (south side). Why does this short section of the wall have such a pronounced bend (just behind)? Whatever the reason, it did help this small section survive the road building that destroyed many miles of the structure west from Newcastle.
