Key Takeaways Copied to clipboard!

  • Hadrian's Wall was constructed as a militarized border control system, intended to stop raids from Caledonia and facilitate controlled crossing and taxation, rather than being an impenetrable defense.

  • Roman emperors Septimius Severus and Constantine Chlorus both died in York while attempting to campaign against the northern tribes in Caledonia/Pictland, suggesting York was an unfortunate stopover for Roman leadership in the region.
