What Are the Special Designs of the Arrow Windows on the Great Wall?

The arrow windows on the Great Wall were designed with great precision and functionality in mind. They were typically narrow and elongated, allowing archers to fire arrows outwards while minimizing the risk of enemy projectiles entering. The height and angle of the arrow windows were carefully calibrated. They were placed at a height suitable for archers to comfortably draw their bows and release arrows, usually around chest to shoulder level. The angle was adjusted to provide the best possible range and accuracy, often slanting slightly downwards to target enemies approaching the base of the wall. Some arrow windows were also equipped with movable shutters or covers. These could be opened when the defenders needed to fire and closed to protect against enemy fire during lulls in the battle. The design of the arrow windows was a crucial part of the Great Wall's defense strategy, enabling the defenders to effectively engage the enemy while maintaining their own safety.
