Polygonal masonry
Polygonal masonry is a technique of stone construction of the ancient Mediterranean world. 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 Mediterranean and sometimes corresponds to the less technical category of Cyclopean masonry.
