Ancient Fire Signals Reborn: Witness the Spectacular “Fryktories” in the Cyclades this Sunday, 31 May 2026
May
If you are lucky enough to be island-hopping in Greece right now, cancel your Sunday evening plans. You are about to witness history quite literally light up before your eyes.
On Sunday, May 31st, 2026, at 19:00 (7:00 PM), twelve islands in the Cyclades will revive Fryktories (Φρυκτωρίες), a breathtaking ancient optical communication system that uses blazing torches to send messages across the Aegean Sea.
Whether you are sipping wine in Santorini or relaxing on the beaches of Naxos, here is why you cannot miss this magical event, and the incredible history behind it.
The Story Behind the Flames: Ancient Greece’s “Internet”
Long before smartphones and satellites, the ancient Greeks needed a way to transmit critical military news across vast distances, fast. Their solution? The Fryktoria network. The word comes from fryktos (meaning beacon/burning torch) and ora (meaning care/watch). Strategically built stone towers, known as fryktorioi, were erected on the highest mountain peaks and coastal cliffs of the islands. Each tower had to be perfectly within the line of sight of the next.
How did it work?
When danger approached, a watchman would light a massive bonfire. The watchman on the neighboring island, scanning the horizon, would see the flame and immediately light his own. This chain reaction allowed messages to travel hundreds of kilometers in just a few hours.
Later, in the 4th century BC, the system was upgraded by Aeneas Tacticus and Polybius into an alphabetic telegraph. By using sets of torches on two separate walls, watchmen could actually spell out specific words, moving from simple “yes/no” warnings to detailed military intelligence.
Fun Fact from Greek Mythology: The most famous use of this system is recorded by the playwright Aeschylus in Agamemnon. When Troy finally fell to the Greeks, the triumphant news was relayed across the Aegean via a chain of mountaintop fires, reaching Queen Clytemnestra in Mycenae within a single night!
What to Expect This Sunday (May 31st)
Organized by the Municipality and Cultural Association of Sifnos, this annual revival is not just a historical reenactment, it is a moving message of brotherhood, solidarity, and shared cultural heritage among the islands.
At 19:00, volunteers and locals will gather at ancient tower ruins and historic castles across 12 Cycladic islands to light the beacons simultaneously.
Which islands are participating?
If you are currently staying on any of these islands, look up toward the highest peaks and historic fortresses at dusk:

Where to Watch in Santorini: The 5 Venetian Castles
The island is maximizing its participation by lighting beacons from all five of its historic Venetian Castles (Kastelia).
-
Oia (Castle of Agios Nikolaos): Already famous for its sunset, the view will be even more magical as the beacon ignites.
-
Imerovigli (Skaros Rock): The ancient medieval capital offers the highest, most dramatic vantage point.
-
Pyrgos: Head up to the hilltop castle for a panoramic 360-degree view of the entire island.
-
Akrotiri: Located on the southern tip, this is an excellent spot to watch the lights connect with neighboring islands.
-
Emporio: Witness the event from the heart of Santorini’s best-preserved medieval fortified village.
💡 Tips for Tourists:
-
Timing: The light is to be fired at 19:00, just as the golden hour begins. Ask the locals, your hotel host or local taverna owners where the neighborhood gathering point is and what time. For example in Imerovigli village, the participants will meet at Malteza Church at 18:00 in order to hike to Skaros Rock since cars don’t approach the cliffside.
Important note:
*If there are any adverse weather conditions the event will still be carried out but instead of fires a Greek flag will be waved*
