Almost everywhere in the world you can find well built dry stone retaining walls and natural dry-laid stone terraces holding back piles and piles of dirt day after day, effectively preventing all manner of material from coming crashing down on to public and private property causing disastrous results. Walls of stone do this important work without so much as a murmur of protest or any detectable shift in loyalty. Unfortunately for the most part these structural 'stone warriors' are completely ignored.
