Across 11 countries, homes were built into extreme terrain. 🏘️ From Yemen to Spain, communities have used cliffs, caves, rock faces, and steep elevations as housing when heat, defense, or limited flat land made conventional building harder. This kind of vernacular architecture appears in deserts, river valleys, and mountain settlements across multiple regions. The common pattern is practical adaptation. Many of these homes were shaped by local geology and climate long before unusual architecture became a tourism category. #Architecture #VernacularArchitecture #CaveHomes #CliffDwellings #UnusualHomes
