The Romans descended on Britain around 2,000 years ago. They would go on to occupy the lands stretching south to north for 400 years. Much of their legacy remains dotted around the country.
Hadrian's Wall is perhaps the most notable: a 73-mile structure that spans the River Tyne near the North Sea and all the way to the Solway Firth near the Irish Sea.
While the North of England features some of the most breathtaking Roman remains, the Empire did not stop at the border.
The Wall was originally used as a way to mark the base from which soldiers would travel north, towards Scotland, as well as to "separate Romans from the barbarians" as said by Emperor Hadrian himself.
Later on, the Romans invaded Scotland, and established what has been described as one of the "most impressive forts anywhere in the Roman Empire".Insurance Loans Mortgage Attorney Credit Lawyer
