Watch towers are tall structures designed for observation and surveillance. They are often built in strategic locations, such as along coastlines, borders, or in military installations, to provide a wide view of the surrounding area. Historically, watch towers have been used for signaling and communication, as well as for defense against potential threats. These towers can vary in design and materials, ranging from simple wooden structures to elaborate stone edifices. Many ancient civilizations constructed watch towers as part of their fortifications, while modern versions may incorporate technology like cameras and radar systems for enhanced monitoring capabilities.
