Why were the signal towers built into the Great Wall of China?

The signal towers were platforms or towers built on the tops of hills or other high points along the wall for the best visibility. used to send military communications by beacon. These communications were conveyed by fires or lanterns during the night or by smoke signals in the daytime. Communications were also sent from the signal towers via raising banners, beating clappers, or firing guns. The lower levels of the signal towers contained rooms for soldiers, who lived there while they were defending the boundary. The signal towers (sometimes called beacon terraces, kiosks, or smoke mounds) also held stables, sheepfolds, and storage areas for supplies and weapons.
