Polygonal masonry is a technique of stone 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.

In Italy it is particularly indicative of the region of Latium, but it occurs also in Etruria, Lucania, Samnium, and Umbria; scholars including Giuseppe Lugli have carried out studies of the technique. Some notable sites that have fortification walls built in this technique include Norba, Signia, Alatri, Boiano, Circeo, Cosa, Alba Fucens, Palestrina, and Terracina.
The so-called Porta Rosa of the ancient city of Velia employs a variant of the technique known as Lesbian masonry.
