Hadrian’s Wall (Vallum Aulium) was a defensive fortification in Roman Britannia that ran 73 miles (116km) from Mais at the Solway Firth on the Irish Sea to the banks of the River Tyne at Segedunum at Wallsend in the North Sea.
The purpose of the walls construction varies, some theories by archaeologists suggest that it was an expression of Rome’s power to solidify Hadrian’s policy of defence. On Hadrian’s accession to the throne in AD 117, there was unrest in parts of the Empire, including Judea, Libya, Egypt, and Mauretania which may have persuaded Hadrian to strengthen frontier borders.
