How Big Were the Beacon Towers on the Great Wall

The size of the beacon towers on the Great Wall differed based on their location and strategic importance. Generally, the base of a typical beacon tower could measure around 10 to 15 square meters. They were usually square or rectangular in shape. The height varied from about 5 to 15 meters. In more critical areas, such as those overlooking major passes or valleys, the towers were larger and taller. Their construction was sturdy, using stone and brick materials. The interior often had a small chamber at the base for storing firewood, signal equipment, and sometimes provisions for the guards. The upper part was designed for the sentries to have a clear view of the surroundings. The openings and windows were carefully placed to maximize visibility while minimizing the exposure of the guards to potential enemy attacks. These towers were not only a crucial part of the communication system but also served as mini-fortresses, providing a vantage point for defense and early warning.
