watchtowers
Tall guard posts
Watchtowers are tall structures built for observation and surveillance.
Guards or sentries stationed in watchtowers can see approaching threats from a distance—along borders, at prison perimeters, or on fortified walls.
The word evokes vigilance and guarded boundaries: Watchtowers lined the camp's fence.
Bob Dylan's "All Along the Watchtower" uses the image for apocalyptic atmosphere.
