North at top. The shape of the medieval defences is clearly shown in the modern town plan. The outer 12th century ditch is marked by the outer hedges of the long crofts (fields) on the E and W sides. The SW corner of the Saxon defences is (or rather was) located in the open field, bottom left, next to the building site to its E (which was not excavated or observed archaeologically). Ridge and furrow strips are clearly shown to the E of the town.
