beacon tower
Coastal warning light
A beacon tower is a tower built to hold a fire or light signal, historically used to warn of enemy approach or guide travelers and ships.
The term often appears in historical or fantasy contexts: Beacon towers lined the Great Wall of China.
In Tolkien's Middle-earth, beacon towers relay urgent messages across vast distances by lighting fires in sequence.
