A massive wildfire erupted Tuesday in the Fontainebleau forest, burning approximately 1,900 hectares [2] of land southeast of Paris.

The scale of the blaze threatens one of France's most significant natural landmarks and has forced a large-scale emergency response to protect residential areas near the forest perimeter.

The fire broke out in the forest located about 40 miles [1] southeast of Paris. Local officials described the event as being of an exceptional scale. Julien Gondard, the mayor of Fontainebleau, said, "We’ve never seen anything like this."

Emergency services coordinated the removal of residents from the path of the flames. Laurent Nuñez, the French interior minister, said about 900 homes [1] have been evacuated so far. Nuñez said that no homes have yet been damaged and no one has been injured.

French authorities have launched an investigation to determine how the fire started. The cause of the blaze remains unknown as crews continue to battle the perimeter of the 1,900-hectare [2] burn zone.

Firefighters are working to contain the spread to prevent further evacuations. The proximity of the forest to the capital has heightened the urgency of the containment effort, though officials maintain that residential structures remain intact for now.

"We’ve never seen anything like this."

The intensity of the Fontainebleau fire highlights the increasing vulnerability of European forests to extreme wildfire events. While the lack of casualties and structural damage is a positive immediate outcome, the loss of 1,900 hectares of protected land represents a significant ecological blow to a region critical for biodiversity and tourism near Paris.
