Polygonal masonry

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.^[1]

This technique is found throughout the world and sometimes corresponds to the less technical category of Cyclopean masonry.^[2]

In Italy, polygonal masonry 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.^[3]^[4] Some notable sites that have fortification walls built in this technique include Norba, Signia, Alatri, Boiano, Circeo, Cosa, Alba Fucens, Palestrina, and Terracina.^[5] The Porta Rosa of the ancient city of Velia employs a variant of the technique known as Lesbian masonry.^[1]
