#2: Hadrian’s Wall: England and Scotland

Constructed over six decades in AD 122, Hadrian’s Wall marked the Roman Empire’s boundary. Famously set 73 miles from Scotland due to the Romans’ fear of the Scots, it showcases historical apprehension among these ancient civilizations.

Currently, the magnificent Hadrian’s Wall, no longer a boundary, stands as a significant archaeological wonder. With close to 10% still visible, it spans England’s landscape, offering a glimpse into the past.
