Dry stone is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their unique construction method, which is characterized by the presence of a load-bearing facade of carefully selected interlocking stones. Dry stone technology is best known in the context of wall construction, but dry stone artwork, buildings, bridges, and other structures also exist. A dry stone wall, also known as a dry stone dyke, drystane dyke, dry stone hedge, or rock fence, is a wall constructed from stones without mortar to bind them together. As with any dry stone construction, the structural integrity arises from compressional forces and the interlocking of the stones. Such walls are used in building construction, as field boundaries, and on steep slopes as retaining walls for terracing. (Wikipedia)
