Polygonal masonry

The twelve-angled stone, Hatunrumiyoc street, Cusco, Peru

Polygonal masonry consists of stones that have five or more face angles, in contrast to ashlar blocks which have four rectangular ones.[1]

In Greece, Cyclopean masonry was the first type of polygonal masonry.[2] To fit the stones properly to each other, masons would utilize strips of lead to form templates of the already laid blocks, which were then used to shape the to-be-adjoined ones.[3]

Italy

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.[4][5] Some notable sites that have fortification walls built in this technique include Norba, Signia, Alatri, Boiano, Circeo, Cosa, Alba Fucens, Palestrina, and Terracina.[6] The Porta Rosa of the ancient city of Velia employs a variant of the technique known as Lesbian masonry.[1]
