Hadrian's Wall stretched approximately 73 miles (about 117 kilometers) across northern England. Built under the Roman Emperor Hadrian starting in AD 122, it marked the northern boundary of the Roman Empire in Britain. The wall featured a series of forts, milecastles, and watch towers, serving both as a defense and a means of controlling trade and Immigration. Today, it remains a significant historical landmark and UNESCO World Heritage Site.
