Built by the Roman Emperor Hadrian in 122 AD, Hadrian’s Wall stands as a testament to ancient engineering and military prowess. Spanning 73 miles across the rugged terrain of northern England, it represented the northernmost frontier of the Roman Empire in Britannia. This remarkable feat of construction served dual purposes, as a formidable defensive barrier against invaders and as a means of controlling trade and movement within the empire. Forts, watchtowers, and gates along its length underscored its strategic significance in safeguarding Roman interests in the region.
