The Forth Rail Bridge and the #Falkirk Wheel are two of Scotland's iconic feats of engineering, but did you know that one of the country's most ambitious construction projects dates back to 142 AD? The Antonine Wall, lined by 17 forts and patrolled by 7,000 soldiers, stretched from the Firth of Clyde to the Forth.
