We had a good look around the site of the original fort built at the start of the wall. They claim it may have been designed, at least partially by Hadrian himself I think "may" is the key work here. At this point there is very little original remaining as like in so many like this, where a city built up around fortifications, the building materials have been mostly cannibalized to be used in the construction in newer buildings. There are some remnants of the original was here but for the most part the city has been built over it.
We are off in an hour or so. Most of the day is through Newcastle, along the river valley. Interesting but not to "Roman".
