Newcastle (Pons Aelius) Bridge, Vallum and Fort (info needed

[PhilusEstilius]

I don't think your wrong Yuri for I've just had another look at that drawing then at Google earth, if the dotted line is to be considered the supposed fort wall the south end would fall over not exactly what is a cliff but what is a very steep gradient. The supposed fort is just too elongated to be true infact almost twice the size it should be, I think it would be a push to even get 4 barrack blocks into.
