Four American tourists were among six people killed when a powerful explosion flattened a two-story residential building in the heart of Athens’ historic Plaka district Friday morning, at the foot of the Acropolis.
The four Americans were believed to be two couples who had planned to board a 3 p.m. flight out of the Greek capital later that same day. The two other people killed were believed to be an elderly couple who lived in an apartment in the building.
Plaka, a warren of narrow lanes and low buildings pressed against the slope beneath the Acropolis, is the city’s tourist district and among the most heavily trafficked corners of Athens. The blast turned one of its residential blocks into a mound of rubble.
What the Blast Left Behind
The force of the explosion carried well beyond the structure that collapsed. Surrounding buildings were damaged, and debris was scattered across three blocks. Video footage from the scene shows vehicles, neighboring homes and a church struck by falling rubble.
Concrete, wreckage and household belongings lay strewn across the street — the ordinary contents of people’s lives pulled into the open by the collapse. Two women in an adjacent building were reportedly injured.
The building that came down was a modest two-story structure, the kind that lines the older streets of the district and sits shoulder to shoulder with its neighbors, leaving little buffer between one facade and the next.
A Tribute From the U.S. Ambassador
U.S. Ambassador to Greece Kimberly Guilfoyle paid tribute to the victims in a post on X. “I am deeply saddened to learn of the death of four American citizens in yesterday’s explosion in central Athens,” she wrote.
The deaths give the disaster a reach far past the neighborhood where it happened. For the two American couples, Plaka was a last stop on a trip that was hours from ending; for the elderly couple believed to have died alongside them, the building was home.
A Suspected Gas Leak
Athens Mayor Haris Doukas said the explosion was likely caused by a gas leak. The cause has not been confirmed, though Doukas indicated that gas infrastructure was probably involved.
Gas service runs beneath and through a dense historic quarter where buildings are old, tightly packed and, in many cases, converted to short-term rentals for the visitors who fill Plaka’s cafes and souvenir shops year-round. An explosion in that setting does not stay contained to one address, as the damage to the church, the parked cars and the surrounding homes made clear.
The area sits within a short walk of the Acropolis and the pedestrian streets that funnel millions of visitors toward it each year — which is part of why a single residential collapse there produced an international casualty list rather than a purely local one.
For now, the official account rests on the mayor’s assessment: a probable gas leak, a leveled building, six people dead and two more injured next door. Until investigators complete their work and confirm what ignited inside the two-story structure, that remains the extent of what has been established about the blast that tore through one of the most visited neighborhoods in Europe.
