A watchtower is a tall structure built to observe and watch for any danger or threats in the surrounding area. Watchtowers are often found in places like fortresses, military bases, and along borders. They can also be used in prisons, game reserves, and wilderness areas to monitor activities. The word watchtower refers to a place of observation and vigilance, so it can also be used in a metaphorical sense to describe a person who is vigilant and alert.
