The area we now call Scotland was terribly afflicted by the Roman Empire and was subjected to nearly three centuries of Roman Invasions, campaigns and military occupation. All of Scotland's many roman remains are of a military nature (ie. no public bathouses, circuses, villas or temples). The Gask Ridge Frontier which runs from Braco to Perth formed the earliest known Roman military frontier in the world was built around around AD 79. A massive Legionary fortress was built a few years later at Inchtuthill near Meikleour by Agricola following the decisive battle of Mons Graupius. Campaigns continued throughout the time of the Antonine Wall in the 2nd Century. Septimus Severus later built a huge new base at Carpow near Newburgh further down the Tay to run punishing campaigns in the North East in ther early 3rd century.
England and Wales were only afflicted for a few years until they all started wearing togas, building villas and sitting around in bathhouses singing "'decem urnae pendent ex muro".
