A powerful explosion ripped through a three-storey building in Plaka, one of Athens' most visited neighbourhoods, early Friday, collapsing the structure into rubble. Two bodies — a man and a woman — were recovered from the debris by Saturday, and four people remained missing as rescue teams combed the site with sniffer dogs. About 30 firefighters were on scene, though the operation was slowed by fears that damaged sections and neighbouring buildings could give way.

The timing and location make this a story that lands hard with holidaymakers. Plaka sits at the foot of the Acropolis, packed with hotels, tavernas and short-term rentals, and the collapsed building reportedly housed a holiday apartment occupied by four American tourists. Police said the two men and two women were due to check out that morning for a 3:00 p.m. flight from Athens, but never arrived at the airport. An elderly couple was believed to live in the building. Several other people were hurt, including two women injured in an adjacent property, and an unconscious woman was taken to hospital by ambulance.

The blast, which struck at around 7:30 a.m., scattered concrete and twisted metal across surrounding streets, damaging parked cars, nearby homes, shops and a church whose pastor moved Sunday's service outdoors. No cause has been confirmed, but investigators are working on the theory of a gas leak — residents reported smelling gas beforehand, and Athens Mayor Haris Doukas said the explosion appeared likely linked to gas infrastructure.

For anyone with a trip to Athens booked, the practical takeaway is simple: Plaka is a small, dense neighbourhood, and this was a single-building incident rather than a threat to the wider city. The Acropolis, the Temple of Olympian Zeus and the rest of central Athens remain open for business. Still, it's a reminder to note your accommodation's exact address, keep your phone reachable on travel days, and if you ever smell gas in a rental or hotel, alert staff and leave rather than waiting it out. Travellers heading to the streets immediately around the collapse site in the coming days should expect cordons, diverted walks and possible disruption as investigators finish their work.

The search for the missing was continuing as of Saturday, with authorities treating the site as unstable and nearby residents evacuated.
