Living in Greece? Mark your calendar for Wednesday, October 1, 2025—because things are about to get loud. Sirens will howl, church bells will hammer for minutes on end, and for a brief moment, you might wonder if you accidentally woke up in a war movie.
But relax—it’s not the end of the world. It’s just Greece’s annual mega military drill, “PARMENION 25.”
What’s going on?
Every year, the Greek Armed Forces roll out this nationwide test to make sure the alarm system still works. Think of it as a giant sound check for Greece’s emergency warnings: “Do the sirens scream? Do the bells boom? Good, all set.”
This year, church bells are chiming in too—three solid minutes of rapid ringing. Add the sirens, and you’ve got yourself quite the soundtrack.
When will it happen?
The first siren kicks off at 11:00 a.m., followed by a series of signals in different regions until about 12:55 p.m. Some will sound like a rising and falling wail (air raid alert), others will be steady tones (end of alert), and a few longer ones simulate chemical or radiological warnings.
Translation: it’ll be noisy—but the only thing you need to do is maybe calm your pets.
Should you worry?
Not at all. Officials have repeated over and over: this is just a drill. Nobody’s invading, no UFOs are landing, and no natural disaster is brewing.
Pro tip: If you’ve just moved here, don’t be alarmed when it happens. Greeks are so used to it they barely notice—it’s just part of the yearly routine.
Our take
Sure, it’s “only a test,” but it’s also a good chance to learn the different signals. These are the exact sounds you’d hear in a real emergency. Consider it a free crash course in Greek civil protection.
