📍 Phryctories

Phryctoriae (also called Fryktorias) were ancient Greek towers built on selected mountaintops for visual communication—typically spaced 20 miles apart so one tower could signal the next. Their name derives from Greek 'phryktos' meaning 'lit' or 'burning,' relating to fire or torch signaling. The towers were used to transmit prearranged messages across distances, with one tower lighting its flame and the next responding. Some scholars have theorized that such fire beacon systems may have inspired the myth of a signal chain from Troy to Mycenae during the Trojan War.
