As temperatures soar across France, the troglodyte village of Trôo is drawing attention for an unusual advantage: homes carved directly into rock that stay cool even during extreme heat.
Located north of Tours, the village is known for its cave dwellings, some of which are still inhabited today. Residents say the thick layers of surrounding rock maintain a stable indoor temperature throughout the year, reducing the need for air conditioning in summer and helping retain warmth in winter.
