In ancient to modern times, they were used to enclose settlements. Generally, these are referred to as '''city walls''' or '''town walls''', although there were also [[wall]]s, such as the [[Great Wall of China]], [[Hadrian's Wall]], and the metaphorical [[Atlantic Wall]], which extended far beyond the borders of a [[city]] and were used to enclose regions or mark territorial boundaries. Beyond their defensive value many walls also had important symbolic functions — representing the status and independence of the communities they embraced. {{military-stub}} [[Category:Defensive walls| ]]
