What is Watchtower?
[[File:Hirlimann-tour-de-garde.jpeg|right|thumb|A Watchtower.]] {{for|the magazine|The Watchtower}} A '''watchtower''' or '''watch tower''' is a [[tower]] used for [[surveillance]]. They were used at city walls to see invaders, when they were far away, so the city could prepare for an attack. A watchtower is also used for watching over people (like a town or a city). Watchtowers were popular in the [[Middle Ages]]. They are still often used to watch over [[prisoner]]s and make sure that they don't escape or leave the area. [[Forestry]] uses watchtowers to find fires before they become more dangerous. [[Category:Towers]] {{stub}}
