it was still a walled city, the walls were all virtually intact, the castle was a bit ruinous, but it was there, and it had its four main gates, erm east gate on the important london road going out past magdalen and over magdalen bridge, erm the north gate here, the westgate by the castle, and then still existing then but not in your map if you can find it, the south gate across the road, just at the bottom of christchurch, can you find christchurch on your map? erm now, perhaps you can that there's a difference in christchurch on your map with this one.
