The Acropolis, Athens’ crown jewel of ancient Greek ruins, suspended operations Tuesday afternoon as a dangerous heatwave pushed temperatures toward 42°C (107°F) across Greece. The UNESCO World Heritage Site will remain closed from 13:00 to 17:00 local time, marking the third such shutdown this summer due to scorching conditions that now threaten much of southern Europe with wildfires.
Greece’s culture ministry ordered the temporary closure of the 2,500-year-old citadel to protect both visitors and staff from heatstroke, with similar precautions taken during last July’s record heat.
The site, which attracts 15,000 daily visitors and has seen 4.5 million tourists in 2024 alone, sits exposed on Athens’ rocky plateau where temperatures are forecast to reach 38°C. Simultaneously, the labor ministry mandated a five-hour work stoppage for all outdoor laborers in high-risk zones during peak heat hours.

Category 5 Wildfire Alert: Greece Braces Up for Escalating Crisis
Meteorologists warn the heatwave will intensify Wednesday, with Attica, Central Greece, Peloponnese and Thessaly under a rare Category 5 wildfire alert – the highest emergency level indicating extreme fire risk.
This follows 41 blazes reported nationwide Monday, seven of which remained uncontrolled overnight. Civil protection authorities have placed emergency crews on standby and urged citizens to avoid unnecessary travel as the mercury climbs toward 41°C before Thursday’s expected cooldown.
Why It Matters
The Mediterranean heat dome has triggered parallel emergencies across the region. In Spain’s Catalonia, 18,000 residents near Tarragona were confined as 300 firefighters and military units battle a 3,000-hectare blaze. France shuttered Marseille Provence Airport due to encroaching flames, while the A9 autoroute linking to Spain closed near Narbonne. Both nations still bear scars from June’s historic heatwave that shattered temperature records.
The UN Intergovernmental Panel on Climate Change confirms these extreme events reflect a worsening pattern, with human-induced global warming making Mediterranean heatwaves 100 times more likely. As the planet continues heating, scientists project such temperatures will become routine by 2035, with longer durations and higher peaks threatening both cultural heritage and human health across southern Europe.
