Mud walls, often seen as the poorer relative to stone, have stood the test of time as well, if not better than their stone counterparts. Among the most ancient and famous walls found today are those made of mud. Civilizations that built their fortresses of mud didn’t need great quarries lying nearby or have to cut and transport stone at great effort and cost. A well-built mud wall could last centuries. Earth pounded in a wooden frame could be built in any width, and outlast stone.
Today, the use of mud as a building material is declining and Tibetans in rural areas are finding bricks less labor intensive. But a mud building has infinitely more qualities than a cheaply built brick one, is warmer in winter and cooler in summer, though only time will teach this lesson.
