With reference to your edit,Tony,it has just been recently dicovered that there were 3 defensive barriers erected by the romans in north Britain.
The most northerly is Gask ridge ,it's a roman road with signal stations and forts running the length of it.
Then further south there is the Antonine wall (made mostly of turf & wood .
And last there is Hadrians wall (the most famous).
The Roman campaigns in Brittania were largely unsuccessful and very expensive both politically and financially ,they expected hoards of gold and lush
fields of grain ,but all they ended up with was mostly slaves and less precious metals.
Anyway, I think the expansionist designs of the Romans helped lead to their downfall.
