signal fires
Hilltop communication blazes
Signal fires are fires lit to communicate over distance—to summon help, warn of danger, or announce an event.
Before modern communication, they served as beacons across hilltops or watchtowers: The signal fires were lit when enemies approached.
The practice survives ceremonially and in emergency situations.
