On our way to Scotland to visit our children (her son my daughter) Karen and I traveled along Hadrians wall in Northumbria. Karen had passed close by inreign the past but had never managed to get to see it. I had been there several times but not for a while and had even walked a length of it when Mike and I walked the Pennine way some 30+ years ago.
The wall was built during the reign of the roman emperor Hadrian started in AD 122 it took around 6 years to build. It was the northern frontier of the empire and was 80 roman miles in length.
