Polygonal masonry

From Wikipedia, the free encyclopedia
Jump to: navigation, search

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.[1]

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

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.[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]
