A
watchtower is a type of
fortification used in many parts of the world. It differs from a regular
tower in that its primary use is military, soldiers and from a
turret in that it is usually a freestanding structure. Its main purpose is to provide a high, safe place from which a sentinel or guard may observe the surrounding area. In some cases, non-military towers, such as religious
pagodas, may also be used as watchtowers.
