cubile

A cubile is a type of traditional dwelling found in certain rural regions, particularly in parts of Spain. These structures are typically built partially or fully underground, often dug into hillsides or soft earth. The primary purpose of this subterranean construction is to take advantage of the earth's natural insulation, which helps to keep the interior cool in the summer and warm in the winter. This makes them an energy-efficient housing solution, especially in climates with significant temperature fluctuations.

Cubiles are often characterized by their simple, rustic appearance. The exterior may be exposed earth or a low, whitewashed facade. The interiors are usually modest, with basic furnishings. The construction method involves excavating a space and then reinforcing the walls and ceiling, often with stone, wood, or brick. In some areas, cubiles are still inhabited, while in others, they have been repurposed as seasonal dwellings, storage areas, or tourist accommodations. The practice of building cubiles is an ancient one, reflecting a deep understanding of local materials and environmental conditions.
