context_page_description: Polygonal masonry is a technique of stone wall construction. True polygonal masonry is a technique wherein the visible surfaces of the stones are dressed with straight sides or joints, giving the block the appearance of a polygon.
  This technique is found throughout the world and sometimes corresponds to the less technical category of Cyclopean masonry.
