How the Picts must have laughed, as they crossed back and forth, between the Border Patrol posts!
The Romans later built a line of fortified posts along the Danube, to keep the Goths out. But the Goths just laughed uproariously, and came and went as they pleased, all the while thumbing their noses at the Romans!

Maybe it will serve well as a linear nature reserve. Large parts of the old Iron Curtain are now doing a good job of providing wildlife with a much needed safe corridor.

Thank you it was great.

Yes,..knew and have visited the site of part of the wall on the Forth (east) side. The Romans found the Scots too troublesome and fierce. That combined with troubles at home in Rome and elsewhere in the emplre made them abandon the territory between the two walls...the lowland belt of Scotland or Caledonia as it was called by the Romans. The tribe was actually the Picts...the name of the native tribe in these parts. The Scots came over from Ireland at a later date and overthrew/amalgamated with the Picts, and they are the ones who gave their name to the country we now know as Scotland.

Love your history lessons!
