In the past, many important towns and cities were defended by walls, but today only Chester, England has a complete circuit around the city. The Walls are about two miles long and were first built by the Romans nearly 2,000 years ago. They were extended and developed in the Saxon period (10th century).
I see all those little windows on the right side; for bows and arrows I presume. Is there a walkway on top of this; certainly along the inside walls for people to be at those little windows.
I would think so Sylvia, but did not confirm.
