Traditional village houses in Soria use stone, earth, and straw to stay cool in July and hold warmth in January, despite the region’s harsh winters and scorching summers. Built long before electricity, they need neither air conditioning nor basic heating.
Measurements from the La Riba de Escalote station, reported by AEMET, show just how extreme Soria’s climate can be. The station sits at 1042 meters and records temperatures hourly and daily, as well as extremes. The figures capture the challenge of living here.
Research from the University of Granada notes that cave and rock-cut dwellings in Spain are adapted to extreme temperatures and low rainfall. They also offer impressive energy efficiency and a reduced ecological footprint.
The walls do much of the work. Builders used limestone, rough stone, or schist, sometimes mixed with adobe and rammed earth packed with straw. Some walls are 80 centimeters thick. Their mass absorbs heat and releases it slowly, keeping indoor temperatures steady even as conditions outside swing wildly. The walls act as both armor and battery.
Mass alone isn’t the answer; the layout matters too. Upstairs, a desván attic traps air and shields the rooms below from the roof’s heat or cold. Below, a bodega dug into the earth stays cool all year and steadies the floor above. In summer, it’s a refuge; in winter, it gives off gentle warmth.
Builders watched the sun, positioning houses to catch winter light and block the worst of the summer glare. Thick walls and smart orientation work alongside stacked spaces. Heraldo-Diario de Soria calls it a home that “climatizes itself.” No carbon footprint. No wasted energy.
Modern homes chase comfort with machines; rural Soria achieved it through design. These houses use almost no energy and work with nature, not against it. Urban apartments, including those in a recent Madrid case, face rising costs and waste. Soria’s old homes avoid that trap.
This is more than nostalgia. As climate swings worsen, these thick-walled houses show what ability to recover can look like.
