Indian polygonal masonry dates to roughly 1400 AD, making it about 2,000 years younger than European examples. Built from hard carved stone using iron tools, these walls define temple platforms, palace bases, and fortification enclosures. Like Mediterranean polygonal masonry—which is famously used for fortification walls at sites such as Norba, Signia, Alatri, Cosa, and Palestrina—Indian polygonal work serves both structural and defensive purposes, rather than functioning as a purely load-bearing technique.

Key Facts

• Indian polygonal masonry is dated to approximately 1400 AD, roughly 2,000 years younger than European examples
