A fortification usually used to protect a [[city]], [[town]] or other settlement from potential aggressors. The walls can range from simple palisades or earthworks to extensive military fortifications with [[tower]]s, bastions and gates for access to the city. They are commonly seen in [[medieval]] settings. One of the real life examples is the [[Great Wall of China]].
