From very early history to modern times, walls have been a near necessity for every city. [[Uruk]] in ancient [[Sumer]] ([[Mesopotamia]]) is one of the world's oldest known walled cities. Before that, the [[proto-city]] of [[Tell es-Sultan|Jericho]] in the [[West Bank]] had [[Wall of Jericho (Neolithic)|a wall]] surrounding it as early as the 8th millennium{{nbsp}}BC. The earliest known town wall in Europe is of [[Solnitsata]], built in the 6th or 5th millennium BC.
