Watchtowers, also known as lookout towers or observation towers, are structures built for the purpose of surveillance and monitoring a specific area. They are often found in strategic locations, such as mountains, hills, or coastlines, where there is a need to keep an eye on the surroundings. Some other synonyms for watchtowers include lookout posts, watch stations, guard towers, sentinel towers, and observation posts. These words all refer to the same concept of a structure built for surveillance purposes. Today, most watchtowers are used for tourism or recreational purposes, offering breathtaking panoramic views of the surrounding landscape.
