Strategic walls across open country were far rarer, and Hadrian's Wall (from 122) and the Antonine Wall (from 142, abandoned only 8 years after completion) are the most significant examples, both on the Pictish frontier.
Within a year the Antonine Wall was recaptured, but by 163 or 164 it was abandoned.
