French Cave Village Stays Cool Without Air Conditioning
In the troglodyte village of Trôo, France, homes carved into rock maintain a steady 20°C even when outside temperatures hit 35°C. As heatwaves intensify across Europe, this centuries-old housing solution is attracting fresh attention as a climate adaptation model.
While much of France swelters through increasingly brutal heatwaves, residents of a tiny cave village enjoy natural air conditioning that hasn't changed in centuries.
Welcome to Trôo, a troglodyte village north of Tours where homes are carved directly into rock. The thick stone walls keep indoor temperatures around 20 degrees Celsius year-round, even when summer heat outside climbs past 35 degrees.
Dominique Opéron lives in one of these cave dwellings and hasn't needed air conditioning once. The rock naturally regulates temperature, staying cool in summer and retaining warmth when winter arrives.
Jean-Luc Eclercy-Deterpigny, chairman of the local tourism association, calls it "an incredible stroke of luck" in our changing climate. While neighbors in conventional homes crank up energy-guzzling AC units, cave residents simply enjoy the stable comfort their ancestors designed hundreds of years ago.
The village features several kilometers of underground tunnels connecting the inhabited caves. A small number of families still live permanently in these rock homes, carrying on a tradition that suddenly looks remarkably forward-thinking.
The Ripple Effect
Local officials report growing visitor interest in Trôo's ancient housing solution. People aren't just coming for tourism anymore. They're studying how these dwellings work, searching for ways to adapt their own homes as temperatures rise.
The caves demonstrate that sometimes the smartest climate solutions aren't new inventions but old wisdom rediscovered. Energy-efficient, naturally temperature-regulated, and built to last centuries, these homes offer a blueprint that modern architecture is only beginning to appreciate.
France isn't alone in facing more frequent and intense heat. As cities across Europe grapple with deadly summer temperatures, examples like Trôo show that sustainable, comfortable living doesn't always require high-tech solutions.
The village proves that humanity has always been creative about surviving extreme weather, and our ancestors left behind lessons worth learning.
