Hadrian's Wall was a massive Roman fortification built in the second century CE during the reign of Emperor Hadrian. It stretched roughly seventy-four miles across the northern frontier of Roman Britain. The wall's purpose was to consolidate power on the frontiers, serving as a protective barrier against invasions by 'barbarians' outside the Empire's domain. Distinctive features of Hadrian's Wall included small forts, known as milecastles, placed at every mile along its length, with evidence of the wall still existing today.
Emperor Hadrian was known for his extensive building projects and military focus, including the re-building of the Pantheon and the construction of the Temple of Venus and Roma. His desire to leave lasting architectural contributions led to the establishment of various fortifications, such as Hadrian's Wall, reflecting the militarization and Roman cultural imposition over Britain beginning with the earlier invasion by Claudius in 43 CE. The wall marked the northern limit of Roman Britain and was part of a larger network of fortifications that eventually became known as the limes, which included permanent garrisons and fortresses designed to prevent incursions into the Empire.
