Hadrian's Wall, built under Roman Emperor Hadrian around AD 122, primarily utilized locally sourced materials. The stone for the wall mainly came from nearby quarries in the area, particularly from the Whin Sill, a volcanic rock formation. This strategic choice allowed for efficient transportation and construction, as the wall stretched approximately 73 miles across northern England, marking the northern boundary of the Roman Empire.
